for the sweet-hot mustard: 1 cup|250ml distilled white vinegar 1 cup|205 grams granulated sugar 1 (4-ounce|113-gram) tin mustard powder, preferably Coleman’s 1 tablespoon kosher salt (Diamond Crystal or about half as much Morton) 3 large eggs
for the sandwich: 6 tablespoons unsalted butter, room-temp so it’s mayo-soft 8 thick slices soft white bread 12 thick (about ⅛ inch) slices bologna 8 slices American cheese mayo (Duke’s or bust) for swiping sweet-hot mustard for swiping 2 cups|115 grams shrettuce 4 big ol’ handfuls of salt and-vinegar potato chips
Make the mustard: Combine the vinegar, sugar, mustard powder, salt, and eggs in a medium heatproof bowl and whisk until smooth. Pour an inch or so of water into a small saucepan, bring it to a boil over medium-high heat, then lower the heat to medium-low. Set the bowl in the saucepan (without touching the water). Start stirring right away and keep at it, using a rubber spatula to frequently stir and scrape the sides so the eggs don’t have the chance to scramble, until the mixture thickens to a consistency that’s a bit looser than your average Dijon mustard, about 15 minutes. Give it a good whisk to get rid of any clumps. Take the bowl off the pan, let the mustard cool, then cover and refrigerate until it’s fully chilled, 1 hour or so. It’ll thicken a bit more. Use it now or keep it in an airtight container in the fridge for up to 3 weeks.
Make the sandwich: Get your oven to 400°F.
Get a well-seasoned cast-iron skillet or griddle good and hot over medium heat. Swipe the butter on each side of the bread and toast in batches in the skillet until both sides are golden brown, 1 to 2 minutes per side.
When they’re done, move them to a rack or stand them up so they lean against each other, to keep from getting soggy.
In that same skillet, cook the bologna slices over medium-high heat, in batches if necessary, until nice and brown on both sides, about 2 minutes per side.
As they’re done, move them to a baking sheet in slightly overlapping groups of three. When they’re all browned, top each group with two slices of the cheese and stick the pan in the oven until the cheese gets melty, about 3 minutes.
Meanwhile, swipe a socially unacceptable amount of mayo on four of the bread slices and swipe a similarly generous amount of mustard on the other four. Add the shrettuce to the mayo-slathered slices, then the cheesy bologna, then a handful of chips so big that half of them fall off.
Cover with the remaining bread slices and press down on each one with your palm, crushing the chips, so the sandwich can just barely fit in a human mouth. Eat.
