I don’t always make grilled cheese, but when I do, I make a knockoff fondeu from my favorite restaurant that shut down years ago.
It involves mixing sharp cheddar with a bit of Velveeta, some milk, dried mustard, and dark Jamaican rum over heat. Once it is blended I pour it into silicone butter molds and chill it. Once it cools and solidifies I take some of it and spread it generously on sourdough bread and heat with a bit of olive oil in the skillet.
Sometimes I get slightly fancy and get one of those freshly baked loaves of bread from the store, the kind that are very fresh, soft, and still warm. I cut that up instead of using presliced bread.
Mayonnaise, mustard, and a little dill relish. Cheeses are sharp cheddar and gruyere. Bread is either sourdough or rye, depending on the mood. Buttered on the outside and grilled till the cheese oozes out the side. (Sometimes I put bacon in as well.)
i’m used to the cheapo style that the Army fed me, which was usually on wheat bread that was about to go stale with butter flavored vegetable oil and cheese that wasn’t colored orange.
when i buy takeout i get fancy for Monte Cristo style or (rarer, hard to find) Welsh Rarebit
