*Pickled red onions: Thinly slice 1 medium-sized red onion and place in a jar large enough to fit the strips. Bring 1/2 cup water to just a boil. Add 1/2 cup white vinegar, 1 tablespoon sugar, and 1 teaspoon salt to a heatproof bowl. Stir in the hot water until the granules dissolve, then pour over the onions. Cover and rest at least 30 minutes, or transfer to the fridge overnight. Onions keep well for up to 5 days.
