I tried a ham, cream cheese and pineapple sandwich at uni once. I could kind of see the thinking behind it - ham and cream cheese is good, ham and pineapple on pizza is good (not convinced about it in a sandwich), but all three together was just disgusting.
Never, ever again!
Overcooking veg and throw bread/cake when its gone stale. I love stale cake dunked in tea
PEOPLE WHO THROW THINGS OUT A DAY AFTER IT'S USE BY DATE!
irritates the hell out off me! Just give it a sniff and a prod. It's usually fine.
My flatmate puts cranberries in his korma. I can just about understand/tolerate raisins in there, but cranberries?
Eating meat . . .
Please don't flame me.
I can't think of anything so weird that I'd call it a food crime. I didn't used to like it when people rejected the sealed part of a roast (you know, the slightly tougher bit around the outside) but it just meant more for me. That was before I stopped eating roasts, ofc.
I like ketchup but there is a time, place and acceptable quantity. A thin layer for flavor or a pot to dip, but don't douse ANYTHING in it! It's rank in large amounts and quite spoils the food.
I hate it when food reaches my plate that's never seen salt, pepper, herbs or spices. All food needs some sort of seasoning and leaning what/how much is one of the arts of cooking.
I have some weird habits with my food - I'm sure I do things that freak other people out a bit. Rasins and rice crispies in porridge? YES PLEASE!
Oh, big annoyance - throwing food away before the sell-by date, let alone before the use-by date, unless it has gone off prematurely. Good food is good food and unless you have a compromised immune system (or it's a very special case) you'll be FINE. The opposite is also true - I hate people that buy something and then let it fester and go mouldy.
Oversteaming/boiling veg. Boiled veg is generally rank anyway but overboiling it until it is totally impotent and flavorless? Why!?
Favourite greasy pizza topping? Pineapple, mushroom and garlic butter. But only for nasty, take-away pizzas.
EDIT - yay, I got negged for this!
EDIT 2 - that wasn't an invitation to keep negging me.
I remember this guy in high school buying a slice of pizza with beans in the canteen. Really odd combination.
Sweetcorn on pizza works.
