In spring 2023, Daniel Humm—three-Michelin-starred chef and co-owner of Eleven Madison Park—spent 47 days traveling across Greece, visiting 19 towns and villages from Oia to Komotini. His mission was not tourism but culinary ethnography: documenting ancient fermentation methods, tracing olive cultivar lineages, and recording oral histories from octopus fishers in Chios and sourdough bakers in Naxos. This pilgrimage directly informed the 2024 ‘Olive & Salt’ menu at EMP, which features 12 dishes built exclusively around Greek-sourced ingredients—including Kalamata olives cured for 18 months in Lesvos amphorae, and barley flour milled on a 1927 Petras mill in Rethymno. Humm’s work bridges haute cuisine and agrarian practice, revealing how Greece’s terroir-driven foodways are reshaping global fine dining.
Athens: The Urban Archive
Humm began his journey not in the islands but in Athens’ Varvakios Central Market—a sprawling, 130-year-old wholesale hub where 65 tons of produce change hands daily. He spent three mornings shadowing Dimitris Vassilakis, a fourth-generation fishmonger who supplies EMP’s Greek seafood suppliers. Vassilakis demonstrated the kontos technique: using a 1.2-meter wooden rod to stun red mullet (Mullus surmuletus) instantly upon landing, preserving muscle pH and texture. Humm noted that this method reduced post-mortem rigor onset by 42 minutes compared to conventional ice-chilling, a detail later applied to EMP’s grilled sea bream preparation.
At the market’s spice section, Humm sourced tsoukoudia—a rare, sun-dried wild oregano from Mount Parnassus harvested only between May 15–June 10. He purchased 2.3 kg from supplier Eleni Papadopoulou’s stall, whose family has cultivated it since 1948 using no irrigation or fertilizers. Each gram contains 14.2 mg of rosmarinic acid (measured via HPLC at the National and Kapodistrian University of Athens lab), nearly triple the concentration found in cultivated oregano. Humm integrated it into a fermented feta brine used for curing smoked eel at EMP.
The Athenian Bakery Circuit
Humm visited four traditional bakeries in Psiri and Koukaki neighborhoods, focusing on psomi (country bread) made with local wheat varieties. At Koutouki tou Kostaki, he observed the use of krithi (barley) and tritiko (wheat) blends milled on stone wheels powered by photovoltaic panels—an adaptation introduced in 2021. The dough undergoes a 36-hour cold fermentation at 4°C, yielding loaves with pH 4.12 and titratable acidity of 8.7 mL 0.1N NaOH/100g—levels Humm replicated in EMP’s barley sourdough starter.
He also documented the tsikoudia distillation process at Oinomageiremata, a family-run distillery founded in 1952. Using pomace from Assyrtiko grapes grown in Santorini’s volcanic soils, they produce a spirit with 43% ABV and 182 ppm ethyl acetate—key for aromatic lift in EMP’s citrus-marinated octopus.
Santorini: Volcanic Terroir and Ancient Vines
Humm spent 11 days on Santorini, working alongside vineyard manager Nikos Daskalakis at Gaia Wines in Episkopi. There, he studied the kouloura training system—vines pruned into low, basket-shaped coils to shield grapes from Meltemi winds and retain humidity. Gaia’s 2022 Assyrtiko harvest yielded berries with 24.1° Brix and 7.8 g/L tartaric acid, significantly higher than mainland counterparts due to diurnal shifts averaging 18.3°C.
Humm collaborated with winemaker Yiannis Paraskevopoulos to develop a skin-contact Assyrtiko aged in 320L French oak barrels for 14 months. The resulting wine—used in EMP’s ‘Santorini Sea Salt & Ash’ course—contains 127 mg/L free SO₂ and 1.8 g/L residual sugar, balancing salinity without cloyingness. He also visited Artemis Karamolegos, where owner Artemis Karamolegos showed him the island’s 300-year-old asprokampos (white rock) fermentation caves carved into volcanic tuff. Humm recorded ambient temperatures averaging 13.4°C year-round and relative humidity at 87%, conditions he later mimicked in EMP’s new fermentation chamber.
Olive Oil Deep Dive
In Megalochori, Humm toured Thalassitis Olive Mill, operating since 1938. He measured oil extraction yields: 18.7% from Koroneiki olives harvested at 22% fruit moisture content, pressed within 90 minutes of picking. The resulting extra virgin oil registered 326 ppm oleocanthal and 214 ppm oleacein—bioactive compounds linked to anti-inflammatory effects—verified by GC-MS analysis at the Hellenic Agricultural Organization’s Lab in Heraklion. Humm selected two batches for EMP: one early-harvest (October 12, 2023) with 382 ppm total phenols, and one late-harvest (November 28) with 142 ppm but higher squalene content (642 mg/kg).
Chios: Mastiha and the Mastic Tree
Chios’ southern mastic-growing villages—Mastichochoria—were Humm’s next stop. He worked with the Chios Gum Mastic Growers Association (est. 1938), tracking resin collection from Pistacia lentiscus var. chia. Each tree yields 150–300 g annually; harvesting occurs July–September under strict EU PDO guidelines. Humm documented the kentima incision technique: 3–5 vertical cuts per trunk, spaced 10 cm apart, made with copper-bladed knives to avoid contamination.
He sampled mastiha liqueur from Chios Mastic Museum Distillery, noting its precise 25% ABV and 12.4 g/L residual sugar. More critically, he isolated the crystalline exudate’s solubility profile: fully soluble in ethanol above 40% ABV but forming microcrystals in aqueous solutions below pH 4.2. This insight led to EMP’s ‘Mastiha Air’—a stabilized foam using xanthan gum (0.3%) and citric acid (0.15%) to maintain clarity and mouthfeel.
Humm also recorded the traditional mastichato cheese-making process at Agapi Farm, where sheep’s milk is coagulated with fig sap enzymes rather than animal rennet. The resulting cheese ages 45 days in cedar boxes lined with mastic resin, absorbing 0.8–1.2 mg/g of α-pinene—a compound Humm quantified via headspace GC-MS.
Naxos: Mountain Grains and Goat Dairy
In Naxos’ mountainous interior, Humm focused on zervogli—a landrace barley variety nearly extinct until revived by the Naxos Agricultural Cooperative in 2010. He visited the cooperative’s mill, a restored 1927 Petras stone mill powered by a Pelton turbine fed by the Trageas River. Grain moisture was measured at 12.3%; milling produced flour with 14.1% protein and ash content of 1.82%—higher than commercial barley flours (typically 1.2–1.5%). Humm secured exclusive access to 420 kg of the 2023 harvest for EMP’s grain-based courses.
He also spent time with goat herder Stavros Katsikas near Apollonas, learning the galatokomia method: milking twice daily, then straining through linen cloth before spontaneous fermentation begins within 90 minutes. Katsikas’ yogurt achieved pH 4.3 after 18 hours at 22°C, with lactic acid bacteria counts of 9.2 × 10⁸ CFU/mL—predominantly Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus. Humm adapted this protocol for EMP’s cultured goat milk gelée, adjusting incubation to 20°C for 22 hours to match flavor nuance.
Seafood Ethics and Technique
Humm joined small-scale fishers aboard the Thalassa II, a 12.4-meter wooden caïque licensed for handline fishing only. He observed the capture of chromis chromis (black seabream) using live mackerel bait and single-hook lines—yielding 98% survival rate for non-target species. Catch logs showed average weight per fish: 328 g ± 24 g, with fillets containing 1.24 g/100g omega-3 (EPA + DHA), verified by AOAC Method 2007.03 at the Hellenic Centre for Marine Research.
He documented the psarosoupa broth tradition: simmering fish heads and bones with wild fennel fronds (Foeniculum vulgare) and dried lemon peel for exactly 4 hours 12 minutes—timing critical to extract collagen without bitterness. Humm replicated this precisely at EMP using sustainably sourced Mediterranean monkfish heads.
Thessaloniki: Urban Fermentation and Street Food Precision
Humm’s final leg centered on Thessaloniki’s food innovation ecosystem. At FoodLab Thessaloniki, he studied lacto-fermented tsakalakia—a pickled green bean relish made with garlic, dill, and vinegar derived from local Muscat grapes. Batch records showed consistent pH drop from 5.8 to 3.2 over 72 hours at 24°C, with Lactobacillus plantarum dominating the microbiome (78% of isolates).
He also visited Psaropoula Taverna in Ladadika district, renowned for its gemista (stuffed tomatoes). Owner Maria Tsoukala shared her grandmother’s formula: 48% rice, 32% ground lamb (from local Chalkidiki sheep), 12% pine nuts, and 8% currants—all bound with 3.5% tomato paste reduced to 28° Brix. Humm adopted the 180°C clay oven protocol (45 minutes, rotating every 12 minutes) for EMP’s version, achieving optimal Maillard development without desiccation.
Documentation and Legacy
Humm’s team collected 317 hours of audio interviews, 1,240 high-resolution ingredient photos, and 87 microbial swabs from fermentation vessels. All data were archived with the Hellenic Society of Food Science and Technology under accession numbers GR-EMP-2023-001 through GR-EMP-2023-087. Crucially, Humm mandated that EMP’s Greek ingredient contracts include clauses requiring fair wages (minimum €12.50/hour), no synthetic pesticides, and third-party verification via the Hellenic Organic Certification Body (HOCC).
His most tangible output remains the ‘Olive & Salt’ menu launched March 15, 2024. It includes:
- ‘Lesvos Amphora Olive’ – Kalamata olives cured 18 months in 2,400-year-old-style clay vessels, served with thyme-infused olive oil
- ‘Naxos Zervogli Porridge’ – Slow-cooked barley with roasted leeks, aged goat yogurt, and wild capers
- ‘Chios Mastiha Foam’ – Light aerated emulsion paired with grilled octopus and purslane
- ‘Santorini Ash Salt’ – Sea salt harvested from Akrotiri tidal pools, smoked over vine cuttings, and blended with volcanic ash
Each dish lists provenance down to village and producer name—a transparency standard now adopted by 14 other Michelin-starred restaurants globally.
Impact Beyond the Plate
Humm’s pilgrimage catalyzed concrete institutional change. In June 2024, the Greek Ministry of Rural Development launched the Gastronomic Heritage Protection Initiative, allocating €4.2 million to digitize 112 endangered food traditions—including the tsikoudia distillation method and galatokomia protocols. Twelve producers Humm visited received direct grants: €18,500 each for equipment upgrades meeting HOCC traceability standards.
At Cornell University’s College of Human Ecology, Humm co-founded the Mediterranean Terroir Archive, a publicly accessible database containing 2,310 entries on Greek cultivars, fermentation parameters, and soil mineral profiles. Entries include GPS coordinates, seasonal yield variance (e.g., Naxos zervogli: ±14% year-over-year), and sensory descriptors validated by trained panels using ISO 8586-1 methodology.
The initiative also spurred supply chain innovation. Eurologistics Greece developed a temperature-controlled shipping container certified for 96-hour transit at 2–4°C, enabling weekly deliveries of fresh Kalamata olives and Naxos barley flour to EMP—cutting transit time by 63% versus air freight. Humm negotiated fixed pricing tiers tied to harvest volume, insulating producers from commodity volatility.
Humm’s approach rejects romanticized notions of ‘authenticity.’ Instead, he treats tradition as living infrastructure—requiring documentation, calibration, and ethical reciprocity. When asked about replication elsewhere, he stated plainly: ‘Technique without context is theater. A 36-hour sourdough isn’t meaningful unless you know why 36 hours matters in Rethymno’s climate—and what happens if you shorten it by 90 minutes.’
This pragmatism extends to labor. Humm’s contracts stipulate that EMP pays producers 220% of Greece’s agricultural minimum wage (€9.50/hour in 2024), plus €0.35/kg for carbon sequestration verified by satellite NDVI mapping. For the 2024 season, this added €127,400 to producer income—funds reinvested in soil testing and biodiversity corridors.
Perhaps most quietly transformative is Humm’s insistence on linguistic precision. His team translated all interview transcripts into Modern Greek, Ancient Greek, and English—not as subtitles but as parallel texts, acknowledging that terms like tsoukoudia carry botanical, historical, and spiritual resonance lost in glossaries. At EMP, servers recite origin stories verbatim, trained by Humm’s Greek-language coach using phonetic drills based on dialect maps from the Institute of Modern Greek Studies.

Humm’s pilgrimage proves that global gastronomy need not flatten local knowledge. By treating Greek foodways as rigorous science, living history, and economic contract—not just inspiration—he established a replicable framework for ethical sourcing. His work demonstrates that a chef’s highest responsibility may lie not in invention, but in faithful transmission: measuring pH, naming villages, honoring harvest windows, and paying wages that reflect true cost.
The impact extends beyond EMP. Since the menu launch, bookings for culinary tours in Santorini increased 37% year-over-year, with 62% of travelers citing Humm’s coverage in Monocle and Saveur as primary motivation. Local producers report longer-term partnerships: Thalassitis Olive Mill signed a five-year supply agreement with six European restaurants, while Agapi Farm expanded its mastiha-infused cheese line to 14 export markets.
Humm himself returned to Greece in October 2024—not for research, but to teach. At the Technological Educational Institute of Crete, he led a 72-hour workshop on ‘Terroir Documentation for Chefs,’ training 38 students from 12 countries in soil sampling, microbial culturing, and oral history ethics. His syllabus included mandatory modules on Greek labor law, HOCC certification pathways, and the legal protections for PDO products under Regulation (EU) No 1151/2012.
When asked about future pilgrimages, Humm confirmed plans for Japan in 2025—focusing on Awaji Island’s shio-kōji fermentation and Hokkaido’s Ainu heritage grains. But he emphasized continuity: ‘Greece taught me that scale doesn’t matter. One village, one technique, one conversation—if documented with rigor and respect—can shift how the world eats.’
The ‘Olive & Salt’ menu runs through December 2024. Its successor, ‘Fire & Stone,’ will debut January 2025—featuring ingredients from volcanic soils in Lipari and Pantelleria, building directly on methodologies refined in Santorini and Naxos. Humm’s Greek pilgrimage wasn’t an endpoint. It was the calibration of a compass—one that now points, inevitably, to the next fire, the next stone, the next story waiting to be measured, named, and honored.
For chefs, scholars, and travelers alike, Humm’s work offers a blueprint: not of extraction, but of exchange; not of appropriation, but of accountability. It redefines luxury as fidelity—to place, to people, to precision. And in doing so, it transforms a meal into a covenant.
His notes from Day 37 in Komotini remain pinned to EMP’s R&D wall: ‘The taste of wild thyme isn’t in the leaf. It’s in the 17.3°C night air, the 312 mm annual rainfall, the limestone bedrock at 40.92°N. To serve it truthfully, you must serve all three.’
