How to plan a week of multicultural dinners when your family has food allergies

The families eating the most interesting food are also the families with the most complicated allergen math. One week might include adobo, a Korean stew, pasta, tacos, and something with coconut milk — and somewhere in that rotation is a child who can't have peanuts, or a partner who reacts to shellfish, or someone avoiding wheat. Managing that across five different culinary traditions, every week, is a real problem.

The good news is that it's a solvable problem. Every cuisine has safe dishes — often more than you'd expect. The work is front-loading the knowledge so you're not improvising mid-cook, and building a system that makes safe choices the default rather than the exception.

Step 1: Build one allergen profile per household

The household profile is the union of every individual restriction. If one person can't have peanuts and another can't have shellfish, both allergens are off the table for shared meals. List them all in one place before you plan anything.

North America recognizes nine major allergens: milk, eggs, peanuts, tree nuts, wheat, soy, fish, shellfish, and sesame. Most household profiles touch two or three of these. Some touch more. The Listahan app stores this profile and applies it automatically to every recipe, plan, and lunchbox — but even on paper, having the list means you're not holding it all in your head every time you cook.

Step 2: Map allergens to cuisines before you plan

Every cuisine has structural ingredients — the things that make it taste like itself. Some of those ingredients are allergens. Knowing which ones, in which cuisines, before you start planning is the difference between a safe week and a surprised scramble at dinnertime.

• Filipino cooking: Fish sauce, bagoong (shrimp paste), and calamansi are constants. Kare-kare uses peanuts and shrimp paste. Most adobo is soy and wheat (soy sauce).
• Korean cooking: Gochujang and doenjang are wheat and soy. Seafood stock runs through many broths. Most banchan (side dishes) contains soy or sesame.
• Mexican cooking: Mole and some salsas contain peanuts or tree nuts. Corn-based dishes (tortillas, tamales) are naturally wheat-free. Dairy is heavy in Tex-Mex; lighter in regional Mexican.
• Japanese cooking: Soy and wheat are in soy sauce, miso, and most marinades. Fish is foundational in dashi. Sesame appears in many dishes as a garnish.
• West African cooking: Peanut stew (groundnut soup) is a staple. Many dishes use groundnut oil. Fermented locust beans (dawadawa) can be an allergen concern for some.

This isn't a reason to avoid any cuisine — it's a reason to pick the right dishes within it.

Step 3: Anchor each night to a safe base — then pick the dish

The instinct is to think "Filipino night" and immediately go to the most iconic dish. That's fine when there's no allergy in play. With restrictions, reverse the process: start with the cuisine, check the allergen profile, then choose from what's safe within it.

Filipino night with a peanut restriction skips kare-kare (peanuts, shrimp paste) but has plenty of options: tinolang manok (ginger chicken broth), sinigang (tamarind broth), lechon kawali (pork belly, no allergens), or dinuguan (pork blood stew, no allergens). The cuisine stays on the table. The specific dish is the variable.

Korean night with a shellfish restriction skips haemul pajeon (seafood pancake) and sundubu jjigae made with anchovy stock — but doenjang jjigae with tofu and vegetables, japchae (glass noodles), or bibimbap with a plant-based protein are all within reach.

Step 4: Keep two safe anchors per cuisine

For each cuisine you cook regularly, identify two or three dishes that already fit your household's profile. When a week gets complicated — a late meeting, a kid's activity that runs long — you fall back to what you know rather than improvising with unfamiliar ingredients.

These anchor dishes are worth memorizing or keeping somewhere accessible. In the app, saved recipes and the plan screen serve this function. On paper, a notes app or a card on the fridge works.

Step 5: Let the plan drive the shopping list

The most common point where allergens slip in is at the store, not in the recipe. You're planning to make adobo, you grab a bottle of soy sauce without checking — and the specific brand uses wheat as a thickener. Or you pick up a spice blend that has a "may contain peanuts" warning you didn't notice.

Shopping from a plan (rather than planning from what you bought) keeps the allergen check in the right place. The Listahan shopping list generates from the week's plan and flags ingredients by allergen category. For a manual workflow, writing the list from the recipe before you leave the house forces the label-check to happen in your kitchen, where you have time to find a substitute.

Step 6: Read the label on every product, every time

A recipe that looks clean on paper is only as safe as the specific products you put into it. Formulations change. "Contains" statements vary by batch. A product that was safe last year may have been reformulated. A "made in the same facility as" warning can be the difference between a safe meal and a reaction.

This is the step that can't be automated away. Listahan can flag the allergen category; you confirm the specific brand's label at the store. Both checks need to happen every time.

What this looks like in practice

A household managing a nut allergy and a shellfish allergy, cooking across Filipino, Korean, and Mexican cuisines, might plan a week that looks like this:

• Monday: Tinolang manok — ginger chicken soup, naturally nut-free and shellfish-free
• Tuesday: Doenjang jjigae with tofu and zucchini — soy-forward Korean stew, no shellfish
• Wednesday: Chicken tacos with corn tortillas, lime, cilantro — wheat-free, no nuts
• Thursday: Lechon kawali with garlic rice — pork belly, zero allergens
• Friday: Japchae — Korean glass noodles with vegetables and a soy-sauce marinade (verify your specific soy sauce brand)

Five cuisines. One household profile. No compromises on flavor.
