Very bizarre but interesting, I don't think I've ever heard of cheese ever going in a jam, but then again I've never heard of anyone mixing jackfruit with cheese either. Dairy products aren't a part of Khmer cuisine, so butter, milk, and cheese aren't used in Cambodian cooking traditionally.
I am a vegan so I can't taste, but I remember in Ecuador a popular snack was grilled plantains with cheese. I can imagine how certain types of cheeses could compliment sweet flavors though. Very creative of you chef 👩🍳.
