No, they make imitation ice cream now - I’ve seen almond, oat, and coconut milk used. It’s more similar to real ice cream than sorbet is. There’s a noticeable difference but I actually like the imitation ice cream more because it doesn’t have the sour aftertaste I get from milk. The downside is that it’s more expensive; I’ve only ever seen it sold in the premium-priced one-pint containers.
