Allergens

Tag them once on the ingredient and every recipe inherits — including through preps. What that does, and what it does not do.

Who can do thisCreator

Allergens are tagged on the ingredient, once, and every recipe containing it inherits them automatically — including recipes that reach it indirectly through a prep.

This is the single strongest argument for a shared ingredient catalog. If allergens lived on each recipe, one missed edit would be a dish that under-declares, and nothing would tell you which one.

The nine

Edit an ingredient and the dialog offers exactly nine:

Crustacean Shellfish · Eggs · Fish · Milk · Peanuts · Sesame · Soybeans · Tree Nuts · Wheat

These are the major allergens required to be declared in the United States. The list is fixed — you cannot add your own, and that is deliberate: a free-text allergen field produces “nuts”, “Nuts”, “tree nut” and “TREENUTS” in one catalog, none of which can be rolled up reliably.

⚠ An untagged ingredient is a claim, not a blank

This is the most important sentence on this page. Tavorly cannot tell the difference between “this ingredient has no allergens” and “nobody has got to this one yet” — and neither can a server reading the dish.

Imported ingredients arrive untagged, because an import reads a recipe book, and recipe books do not carry allergen data. So after any import, tagging allergens is the work, not a tidy-up.

The reliable pass is to sort by what is obviously implicated — dairy, flour, egg, anything fried in a shared oil, sauces and dressings — rather than reading the catalog top to bottom.

How roll-up works

  • An ingredient carries its allergens.
  • A prep rolls up the allergens of everything in it.
  • A recipe rolls up the allergens of its ingredients and its preps.

So a dish containing a rémoulade containing egg declares Eggs, without anyone tagging the dish. Change the rémoulade’s base and every dish using it re-declares.

That indirect path is exactly the case a human misses, and it is the one Tavorly is best at.

Where they appear

Allergens show in both line views — Front of House and Heart of House — and on the recipe card before a cook opens anything, as pills under CONTAINS ALLERGENS.

That is not redundancy. A server is asked at the table and a cook is holding the pan; both need the answer, and putting it behind a tap for either of them would be wrong. See What each view shows.

What allergens do not cover

Rolled-up allergens say what is in the dish. They say nothing about how it is handled — shared fryers, glove changes, separate boards, a dedicated prep surface.

That belongs in Allergen handling on the recipe’s food-safety block, and it is a different question with a different answer. See Food safety on a recipe.

⚠ Tavorly declares; it does not assess risk. It will faithfully roll up what you tagged. It does not know your kitchen’s cross-contact reality, cannot verify a supplier’s spec, and is not a substitute for your allergen policy or for asking a guest. Getting the tags right is your job; carrying them everywhere, correctly and current, is Tavorly’s.

  • The ingredient catalog — duplicates split allergen work in two, which is why merging matters
  • Prep — the nesting that roll-up travels through
