What makes ice cream gritty?

---

I bought some cherry vanilla ice cream from the grocery store the other day. When I sat down to eat it later that evening, I was totally disgusted by the texture; it was as if someone added a few tablespoons of sand into it. Why, oh why was it like that?

It could have been ice crystals. But if they didn't melt in your mouth, that could mean the sandiness was from lactose crystals:

Temperature fluctuations and poor storage conditions can increase the size of the lactose crystals which give a sandy mouthfeel.

It is probably the ice.. When ice cream isn't made to quality it's, icy tasting! Also, it could have sat in the freezer at the store for too long..
