"scalloped" taters, an Old AF family recipe that was only written down in the last 20 years or so, with no measurements anywhere on the recipe card
oven-safe dish. preferably lidded, but loose aluminum foil works fine too
potates, however many you want or need to use up, sliced as thin as you get can them without a mandoline because no one in the family has ever had one
onions, halved and also sliced thin, quantity relative to how much you like onions
milk (or halfnhalf if you're a decadent lil guy. you can also use unflavored and unsweetened nondairy milk. i've never tried it, but relatives have and reported positive results)
butter, either room temp so you can plop little bits of it or cut into tiny cubes
seasonings (salt, pepper, i've added fresh thyme and sweet paprika before to great success, old bay because i was half asleep and thought it was paprika and it was fine, nutmeg, five spice, go ham)
add a layer of taters to the bottom of the dish, not specified how deep, but flat double layer turns out best by my experimentations. add some onions. sprinkle some seasonings on it to taste. sprinkle some flour on it. again, no measurements, i use at least one heaping big soup spoon's worth of flour per layer, a solid dusting but you should be able to still see the potatoes through it. a few dots of butter. cannot stress enough that this is how the got dam recipe is written
repeat layers until you run out of potatoes, pressing down as needed. you want a little room between the top of the taters and the lip of the dish. or just bake it with a sheet pan on the rack below it if you're paranoid. don't flour the top layer of taters, butter it liberally instead. how much butter do you want? this is a recipe from 1890s southern usa, home of Eating Fat Recreationally, so the traditional answer is "too much"
the strongest vibe check: pour an unspecified amount of milk (carefully) into the potatoes without disturbing the layers. i usually put the milk in my nicest measuring pyrex with the good spout and pour slowly against the side of the dish. "how much milk?" you might ask naively, like i once did. "enough" is the answer i got. i usually pour until i see the whole mass of taters/onions/flour just start floating off the bottom of the dish. top layer not fully submerged but rubbing elbows with the milk. i like saucy potatoes. the temperature of the milk doesn't matter. i've simmered shit like garlic and bay leaf in it before pouring to great success
bake at 375 until it's done. literally word for word what the recipe says, doesn't say to cover it. i do so i can control sauce thickness and browning, but even that isn't necessary. i start checking after 20 mins. when it's done, the taters and onions will be soft all the way through and the milk/flour/butter/seasonings will have thickened into a sauce. how well this sauce hugs the taters and onions will entirely depend on whether my great great great grandmother reached through your spoon to help guide your flour to milk ratio. too runny for your liking, take the lid off and bake it some more. too thick, add more milk, push it around a little bit to mix, and bake it some more. the world is your potato
it's at its best after a 10-15 minute rest, but it isn't necessary. amount made is also relative; i have done a single serving of this in a ramekin with one (1) potato, quarter of an onion, in a toaster oven, all while very very sick, and it turned out splendidly. it's solid comfort food, 20/10 if greatĀ³ gramma possesses you during assembly
