I pressure-cooked a pork butt tonight, and this yellow substance was on it. There's no rotten odor, or anything to suggest it'd gone bad. This had never happened to me before. Can anyone identify it? Is it safe?
Edit: The other ingredients: 4 New Mexico peppers, 1/2 dried Carolina Reaper pepper, 1 onion, 5 cloves garlic, 12 oz beer, 6 cups water, 6 teaspoons chicken bullion.
