2. Make the Sauce
In a small pot, 2 tablespoons of the oil over medium-low heat until shimmering. Add the garlic and cook, stirring, until it begins to brown, 1 to 2 minutes. Whisk in ketchup, rice syrup, gochujang, soy sauce, mirin, and vinegar. Bring sauce up to a simmer, cover with a lid and remove from the heat. Measure out ½ cup and store the remainder in an airtight container for another use.
