Ingredients to avoid —> Peanuts, peanut butter, peanut starch, peanut flour, peanut oil, mixed nuts, crushed nuts, hydrolyzed plant protein, hydrolyzed vegetable protein, vegetable oil (if the source isn’t specified), and depending upon the severity of the allergy, anything that states “may contain trace amounts of peanuts.”

Substitutions —> If your dish calls for peanuts, you might be able to substitute with cashews or sunflower seeds.
