"...if I could inject cubes of cheese with marmite, batter them, and toss them in hot fat.?"
Fried cheese is sort of a thing, right? I'm not sure cheddar would hold up-it would need a pretty thick breading. So then, I start thinking, "Hey, what if I made a marmite and cheese toasty and dipped it in a good beer batter, and fried it?"
I haven't done either yet, but I probably won't be able to sleep tonight unless I do. These, my friends are the things that keep me awake nights.
