I like jam, jelly, and preserves! I've also been meaning to try marmalade for a while now, and fruit butter sounds like it'd be something I'd like too. I don't like eggs unless they're being used to bake something, so I don't see myself liking curd ahaha ;u;
I've liked most jelly/jam flavors that I've tried, apple jelly being my absolute favorite (especially paired with butter, omg), and I'm generally fond of most berry preserves. Oddly, I've never liked purple grape jelly anytime I've had it, even though I like the fruit itself. I don't think I'm particular about the texture/smoothness, though I do prefer them to have minimal to no added sugar. Fruit is plenty sweet on its own, imo, and too much sugar can easily overpower the flavor.
Can't tell you how many apple pies I've had where the filling just tasted like chunky sugar with cinnamon.
Also I just get sick from eating sugar pretty easily ;;
I'll usually have mine on some form of toast, often with a little bit of butter too. Apple jelly or any sort of pink jelly (strawberry, raspberry, etc.) can also go on peanut butter sandwiches, though I've yet to meet a dark jelly that I thought tasted good with peanut butter.
also thumbprint jam cookies are just

. love those.
