A member asked:

Can you get an anaphylactic reaction just by smelling something you are really allergic to?

YES, very dangerous: Anaphylaxis due to inhaling an allergen/mucosal exposure is reported. Examples I have personally encountered in practice are grass pollen, carrots, watermelon, mango and artificial sweetener . Fortunately, this type of reaction is truly rare. Anyone with this type of history should carry 2 epipens, (epinephrine) take a daily antihistamine, and consult an allergy specialist about diagnosis/treatment options.

Not likely: Anaphylactic reactions require ingestion of the allergen. Vapors from foods do not contain the proteins responsible for the allergic reaction.
