What food combinations do you find weird or strange? They could be commonly accepted ones or ones from other cultures. In some or many cases they may not taste all that weird but they just seem wrong to you.
I haven't seen it in a while but one that I remember from my childhood is putting mint jelly on lamb. That's a real wtf combination for me. For me there are very few places where I'll allow mint; mouthwash, candy, and a mint julep, and that's about it.
