I am in the middle of getting my license and had a question. If you use cooking spray on your pans, do you need to list it along with its ingredients on your label? Also, it has soy letchin as an ingredient with a warning in bold stating it contains soy. Does that mean I will have to add it to my list of allergy warnings?

AYes, you have to! And you need to write the allergens: wheat, eggs, milk, soy. Watch out with the ingredients, even wheat flour has more ingredients..

Yes you do, if you want to avoid the extra allergen, parchment paper has no soy warning :)
