S.B.
I like to make a dish my aunt calls "stuff". It's a desserty/jelloy dish. The recipe goes something like this:
Buy whatever kind of jello you want (grape ends up looking grey, though, so I don't make that one unless it's a halloween party and I want something to look like brains) and vanilla ice cream. I like french vanilla, I think it makes it creamier.
Boil water for jello, and mix it with the jello mix in a big bowl. While still hot, wisk in a few scoops of ice cream in until completely melted. Add in more ice cream, mix until melted. Continue until you've used the container of ice cream (I grab the box, I don't know how much that is) or until it won't melt anymore.
Refrigerate in whatever container you want to take to the potluck and refrigerate overnight. If you want, "frost" it with cool whip before serving. Simple and yummy.
(And usually we title it by color. If we use strawberry, call it pink stuff.)
Alternatively to the vanilla ice cream, if you were using say, peach jello you could use peach ice cream and make it extra peachy.
