When measuring flour, we spoon it into a dry measuring cup and level off excess. (Scooping directly from the bag compacts the flour, resulting in dry baked goods.) We recommend salted butter with a higher salt content, such as Kerrygold. Reheating Instructions: In an air fryer: Air fry at 350 degrees F until the bread is warm and the outside is crisp, 2 to 3 minutes. In a toaster oven: Bake at 350 degrees until the bread is warm and the outside is crisp, 4 to 5 minutes.
