Vegetarian

No ingredient line names meat, poultry, fish or shellfish, or things made from them: broth or stock (unless it says vegetable), gelatin and marshmallows, lard, fish sauce, anchovies, and store-bought sauces that usually contain them (Worcestershire, barbecue sauce, oyster sauce, curry paste). Some cheeses, like Parmigiano-Reggiano, are made with animal rennet: check the label if that matters to you.

Optional lines and "To serve" extras don't count, and when a line gives a choice ("vegetable or chicken broth", "rice or naan") one choice that fits is enough: pick that one when you cook.

Nobody picks these by hand: the site works them out from each recipe's ingredient lines, so they update when a recipe changes.
