"It seems perfectly normal to most people round here but chips with gravy, mushy peas, beans or cheese sounds rank. I hate soggy chips - they have to be greasy and well cooked (ie not anaemic) but not soggy."
I couldn't agree more, AndroidAddict - in fact, I would go further and say that gravy spoils anything crispy. It gives me actual, physical pain when I serve beautiful, crispy roast potatoes and yorkshire puddings to dh and the dses, and they pour gravy on them.
But I was raised in a gravy-free household, because my mother didn't like gravy. We were reluctantly allowed ketchup, on certain meals, but she commented every time about the amount of effort she had gone to in cooking the meal, only to have us 'ruin' it with ketchup. Apple sauce was allowable, with pork, ditto bread sauce with chicken or turkey, mustard with beef and parsley sauce with fish or gammon. But not a lot. And to this day, I like certain meals much drier than most people seem to like them.
I do make gravy for dh and the dses - and occasionally I have a small amount on my meal (but it has to be a nice gravy, made with proper stock and wine - not bisto), but it goes in a little pool on my plate, well away from anything crispy, so I can decide what I want gravied and what should not be.
However I also commit many of the food crimes mentioned on here. Dh is very scathing about my liking for wensleydale with mango and ginger. And I love Nutella on toast (especially toasted brioche), salted caramel, peanut butter in things (M&S peanut butter icecream is so delicious, I can't have it in the house - like another poster with peanut butter, I have NO off switch with this particular icecream), and I occasionally enjoy tinned spaghetti hoops on toast - I know it is in direct contradiction to my crispy things should stay crispy mantra - but I bloody love buttery toast with the sauce from the spaghetti hoops soaked into it. Or baked beans and their juice (I eat all the beans and then the squishy toast) - but I will not contemplate baked beans with a cooked breakfast - the juice gets everywhere and contaminates the whole thing.
The worst food crime I can think of is my mother's chopped jelly dessert. Three flavours of jelly, all chopped up finely, and layered in a bowl. Pretty much pre-chewed jelly. I hate jelly anyhow - it is disappointment in see-through, fruit flavoured form - but when chopped up, it is even worse.
