I came up with this combination one day when I'd finally gotten bored with the classic grilled cheese, and I've never looked back. It's not going to solve a craving for grilled cheese with Kraft singles and Campbell's tomato soup, but I've found this classed up sandwich can prompt cravings of its own. With so few ingredients, make sure to choose ones you love. I prefer cheddar so sharp it can bite back, honeycrisp apples, and sourdough bread. For the mustard, I like "moutare a l'ancienne,' which I think just means "made like in the olden days before we had machines to properly pulverize the mustard seeds." —Boston2Berkeley
slices sourdough bread
slices extra sharp cheddar cheese
tart apple (like honeycrisp)
whole grain mustard
In This Recipe
Place your cast iron skillet over medium high heat.
Butter the outside of both pieces of the sourdough bread and spread whole grain mustard on the inside of both pieces (this is messy, there's no way around it).
Slice the apple thinly and layer your sandwich with cheddar then apple slices and sandwich together, mustard side in.
Cook in the hot cast iron skillet until the butter on the top slice of bread has started to melt. Then check your sandwich and flip
