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.) The batter for the buñuelos is quite simple, but frying them requires a bit of practice. Here are some tips for frying them successfully: It is important to use a seasoned rosette mold or the batter will not adhere to it. Heat up the mold in the oil before dipping it into the batter and make sure not to dip the mold more than halfway into the batter. Keep an eye on the temperature of your oil and reheat it between batches if necessary. If you have trouble separating the buñuelo from the mold, use a fork or tongs. Let excess oil on the mold drip off before dipping it into the batter, or the batter may not stick. If your mold is too hot, the batter will cook instantly and slide off the mold.
