Proper marmalade is delicious, but most of the stuff you buy in shops is crap. My father makes his own, and it's gorgeous. Really easy to make, too - just requires a bit of patience, some seville oranges, and no sense of smell while it's cooking.
Lime Marmalade, yes.
Fish Paste (south african achovy spread, nothing like is available here), yes.
Edit - add:
Nutella, yes, I love the stuff.
Honey (creamed and normal with loads of butter), yes!
