David,
I'm not a real doctor, but this definitely sounds like an allergic reaction. Are you allergic to birch pollen? Eating raw apples can give a hot flash reaction. The pollen allergens present in a raw apple would be destroyed by the heat used for a baked apple concoction--which would explain why you don't get
the vapors from eating strudel or pie.
Furthering my theory is the fact that often times a person will crave* or be especially fond of those foods they are allergic to. And it seems that you are particularly fond of those apples.
It all seems harmless enough...maybe even a fun party trick-

*My brother used to have major food allergies, especially to dairy. Instead of vandalization or punk-rock music, my brother's big act of rage against (his own personal) machine would be to secretly procure and ingest industrial size blocks of cheddar cheese, gallons of milk, and carton after carton of vanilla ice cream, only to end up sicker than all get out.
