I've seen a few ice creams with gelatin in them, and I don't buy those, but I'm sure I've consumed it without realizing before. I don't always associate ice cream and gelatin, and to be perfectly honest, if I'm craving it bad enough and I'm at an ice cream shop, I just won't ask. Out of sight, out of mind. This happens maybe once a year mind you, but I'm sure some people are horrified I will knowingly possibly consume gelatin.
