Atlas Patch — Recipe-Driven Gaps

Created 2026-04-22 · Driven by the UMAMI-1 +50 expansion audit · UMAMI-15 adjunct

This patch fills atlas coverage gaps surfaced by the 2026-04-22 slate audit. Each entry uses the standard 3-tier framework from PROCESS.md. These will be folded back into the main category files on the next atlas refresh.


1. Shiso (青紫蘇 · perilla)

Depth: A (→ hamachi-crudo-yuzu-kosho, aceite-verde, tiradito, tuna-tartare)

What to know: Two types. Green shiso (aojiso) = the raw-fish and tempura herb; cucumber-mint-anise note. Red shiso (akajiso) = the umeboshi pigment herb; less used fresh. Leaves wilt within 48 h — must be bought close to use. A pot on the windowsill is the Miami answer (grows year-round in zone 10b). Wholesale microgreen shiso is a restaurant-grade alternative.

Cross-recipe: hamachi-crudo-yuzu-kosho (proposed UMAMI-2), aceite-verde-noma-method (proposed UMAMI-9), tiradito-pargo (proposed UMAMI-2). Also reinforces tuna-tartare-sherry-soy ✅, kanpachi-crudo ✅.


2. Pargo (red snapper, Lutjanus campechanus or L. analis)

Depth: A (→ tiradito, adjunct to whole-fish-kamado)

What to know: Two categories matter. American Red Snapper (Gulf wild) = firm, sweet, ideal for ceviche/tiradito. Mutton Snapper (Florida Keys) = drier flesh but more flavor; local Miami advantage. Avoid "imported red snapper" — 70%+ is rockfish mislabeled. Always ask to see the whole fish or the skin-on fillet.

Cross-recipe: tiradito-pargo-leche-de-tigre (proposed UMAMI-2), alternate to branzino/dorada in whole-fish-kamado ✅.


3. Ají Amarillo (paste, pepper, powder)

Depth: A (→ tiradito; extensible to mojos, sauces, ceviche variations)

What to know: The Peruvian yellow chile (Capsicum baccatum). Medium heat (30k-50k Scoville), fruity and floral. Hard to source fresh outside Peru; paste is the gold-standard US form. Avoid dried powders — they lose the fruit. Look for brands that list only chile + oil + salt (no seed oils, no preservatives).

👑 TIER 3 — Top Shelf

Cross-recipe: tiradito-pargo-leche-de-tigre (proposed UMAMI-2). Extensible to mojos-canarios ✅ as a fusion variant and aguachile-verde ✅ as a heat-layer.


4. Merluza (hake) and Cocochas (hake cheeks)

Depth: A (→ merluza-en-salsa-verde, cocochas-pil-pil — core Basque recipes)

What to know: Merluza = European hake (Merluccius merluccius), the Basque fish. US equivalent is Pacific hake (M. productus) or white hake (Urophycis tenuis, Atlantic). Flesh is flaky-tender, mild, takes sauce beautifully. Cocochas = the throat/chin piece behind the jaw — gelatin-rich, translucent, the pil-pil emulsification engine. A pound of cocochas requires ~50 fish and is a luxury item even in Spain.

Cross-recipe: merluza-en-salsa-verde (proposed UMAMI-4), cocochas-al-pil-pil (proposed UMAMI-4). Also reinforces salsa-verde-basque ✅ (sauce foundation).


5. Squid Ink (tinta de calamar)

Depth: A (→ arròs negre, chipirones en su tinta, salsa brava negra)

What to know: Most shopped-for "squid ink" is actually cuttlefish ink — it's the available form and works identically. Spanish and Italian packets (Nortindal, La Tienda-branded) are 4-8g sachets of pure ink. For real depth use multiple sachets per dish (4-6 g per serving is conservative). Ink from a whole squid you clean yourself has the freshest aroma but tiny yield.

Cross-recipe: arròs-negre (proposed UMAMI-11), chipirones-en-su-tinta (proposed UMAMI-4), salsa-brava-negra (proposed UMAMI-9 — the March 8 cook sauce). Connects to paella-valenciana ✅ and fideuà ✅ as the dark-rice cousins.


6. Entraña / Hanger Steak / Onglet

Depth: B (→ entraña-a-la-plancha)

What to know: One of two "hanger" muscles per steer (the other is skirt/vacío). Mineral, beefy, tender when cut across the grain. Argentina's entraña and France's onglet are the same cut. Medium-rare max — past medium it toughens. One hanger feeds 3-4 people.

👑 TIER 3 — Top Shelf

Cross-recipe: entraña-a-la-plancha-chimichurri (proposed UMAMI-4). Connects to perfect-sous-vide-steak ✅ and chuleton-reverse-sear ✅ as the fast-cook hanger complement to slow-SV/reverse-sear.


7. Chimichurri (chile-herb verde)

Depth: A (→ entraña, extensible to all grilled proteins)

What to know: Argentine table sauce. Parsley + garlic + oregano + red-wine vinegar + olive oil + red-pepper flakes. "Rojo" adds pimentón/ají molido; "verde" is the classical. Best rested ≥1 h for flavor integration; holds 5 days refrigerated. This is an identity sauce: sauces on the side, guest builds the bite.

Sourcing: Pantry-only. Core ingredients covered in files 11-oils-vinegars.md (EVOO + red-wine vinegar), 08-produce-vegetables.md (parsley + garlic), 12-salts-spices-seasonings.md (Mexican oregano, pimentón, red-pepper flakes).

Cross-recipe: entraña-a-la-plancha (proposed UMAMI-4), optional adjunct to chuleton-reverse-sear ✅, kamado-pizza ✅ drizzle, whole-fish-kamado ✅ table sauce.


8. Suckling Pig (cochinillo · lechón)

Depth: A (→ cochinillo-al-carbon — existing stub)

What to know: Traditional Segovia preparation uses a 21-day-old milk-fed piglet (4-6 kg). Skin blisters from fat render + radiant oven heat; at Cándido in Segovia it's carved with a plate to prove tenderness. US suckling pig is typically 15-25 lb dressed, usually 4-8 weeks old (larger than classical Spanish). Smaller is better for skin texture.

Cross-recipe: cochinillo-al-carbon (proposed UMAMI-6, absorbs existing stub). Connects to iberico-secreto-kamado ✅ (Ibérico-pork family) and pimenton-porchetta ✅ (oven-roast-pork family).


9. Milk-Fed Lamb (cordero lechal · cordero lechazo)

Depth: A (→ cordero-lechal-asado — existing stub; lechazo-castellano — proposed)

What to know: Lechal = ≤30 days, nursed only, ≤5.5 kg (Castilian tradition). Lechazo = ≤35 days, ≤8 kg (Tierra de Burgos IGP). Ternasco = 70-80 days, Aragón DOP (already in atlas). True lechal is not commercially imported to the US; the closest approximation is an Elysian Fields (Pure Bred Lamb) "baby lamb" 4-6 week at 5-7 kg — slightly older than Spanish lechal but the only real path.

Cross-recipe: cordero-lechal-asado-castellano (proposed UMAMI-7, absorbs existing stub), lechazo-castellano (proposed UMAMI-7). Connects to lamb-leg-sv-kamado ✅ as the whole-animal roast counterpart to the SV-leg precision play.


10. Tangzhong / Milk Bread (Hokkaido-style)

Depth: B (→ hokkaido-milk-bread-tangzhong)

What to know: Tangzhong is a Japanese roux-preferment: flour cooked in water/milk to 65 °C (starch gelatinization) then cooled and folded into the final dough. Effect: 20-40% more water locked into the crumb, softer/fluffier result that stays fresh 3-4 days (vs 1-2 for regular enriched breads). The technique is Japanese-by-way-of-Taiwan (Yvonne Chen, "65 °C Tangzhong"). The same principle as yudane (Japan's original version, from ≤20 % of the flour pre-scalded).

Sourcing: Pantry-only. Bread flour (≥12% protein) → file 10-grains-legumes-flours.md. Whole milk + heavy cream → file 07-dairy-cheese.md. Japanese-adjacent ingredient: look for Hokkaido "Haruyutaka" bread flour at Momi Market for a summit-tier version. King Arthur Bread Flour is the reliable Tier 1 default.

Cross-recipe: hokkaido-milk-bread-tangzhong (proposed UMAMI-10). Connects to master-sourdough-loaf ✅ (yeasted/sourdough spectrum), focaccia-sheet-pan ✅ (enriched-bread family), and all Japanese-adjacent dishes for a bread course that ties a Spanish-Japanese menu together.


11. Alubias de Tolosa

Depth: A (→ alubias-de-tolosa-con-berza-morcilla)

What to know: Small shiny-black Basque bean (Phaseolus vulgaris), Tolosa DOP (Gipuzkoa). Thin skin, creamy interior, cooks to a deep purple-black broth. The classical preparation is alubias rojas/negras de Tolosa con sus sacramentos (beans + berza cabbage + morcilla + piparras) — the Basque winter counterpart to Asturian fabada. Never add acid (tomato, vinegar) while cooking — it seizes the skin.

Cross-recipe: alubias-de-tolosa-con-berza-morcilla (proposed UMAMI-11). Completes the Spanish-bean-trilogy: fabada-asturiana ✅ (Asturian) + lentejas-estofadas ✅ (Castilian-standard) + alubias-tolosa (Basque).


12. Fish Sauce (for garum + Thai-fusion applications)

Depth: B (→ garum-moderno-koji-method)

What to know: Industrial Asian fish sauce (Red Boat, Megachef) is the reference. Garum is the Roman/Japanese koji-driven version — slower, more umami-complex, less briny. For the proposed garum-moderno recipe, we ferment our own over 10 weeks. But we also want a Tier 2 reference bottle for comparison + emergency use.
