  • 1 serrano
  • 1 shallot (Or sub for 1 small onion and 1 to 2 cloves garlic)
  • 1 cup ketchup
  • 1 tsp cumin

Instructions

Flash Pickled Onions

Set 3 cups of water on to boil.

Add the sugar, salt, vinegar, garlic, black peppercorns, and mustard seed to a jar. Stir to help the sugar dissolve.

Slice the onion into thin, 1/4 inch moons and transfer to a colander or sieve. Once the water is boiling, pour this hot water over the onions.

Transfer the onions to the jar with the vinegar, and stir. Let rest on the counter for 30 minutes if you plan on using them right away, or cover and refrigerate for later usage. They're best during the first week, but will keep for a bit longer.

Chipotle Ketchup

Roughly chop all the chilies and shallot. Remove seeds from the serrano if desired.

Heat about 2 tbs olive oil over medium heat in a medium saucepan. Add the shallot and chilies and cook until softened, about 5 minutes. Reduce heat to low, then add the ketchup, cumin, chili powder, and paprika. Simmer, stirring occasionally, until the color darkens and the sauce thickens, about 15 minutes.

Let cool before storage or use. Can be used right away, and leftovers can be refrigerated for up to a month.

Bison Burgers

Form the ground meat into 4 equal sized patties, making sure to avoid overworking the meat. Sprinkle salt and pepper on each side of the patties.

Grill burgers on a lightly oiled grill rack. Bison is best around medium-rare, so cook it about 3 minutes per side.

We like ours topped with swiss cheese melted directly onto the burger, with a leaf of butter lettuce, and a nicely toasted bun.
