The hole might actually be aenlarged tonsillar follicle. The tonsils can swell in response to infection to help fight bacteria. If a tonsil has been inflamed, it is possible that one or more of the follicles may remain overactive after an infection has passed. The whitish debris that looks like food is actually dead tissue. When the follicle discharges, it will leave a crater behind.

An enlarged tonsillar follicle is not dangerous but can suggest that your tonsils are inflamed. If it keeps bothering you, consult an ENT surgeon.

Awesome! Thanks. It's just a minor annoyance. However, how much of this tissue is there? I generally have an amount that's about the size of sprinkle or two. (Like the elongated ones... "Jimmys" in some places).

hey! i am surprised this is a common irritation! i thought i was the only one with this weird problem of food in the hole on a tonsil... i really now doubt whether it is tissue as when i eat a few biscuits i feel that the " tissue" debri is being replaced with fresh bits by itself all the same my mouth reaks and is vv unpleasant.

Try looking into that route. Google the word tonsillith. I have a similar problem with food getting stuck in the back of my throught. This is not my condition but it sounds exactly like what you're talking about. You can find alot more info about it. I still don't know whats wrong with me.
