Tender Swedish meatballs smothered in a velvety gravy may be the ultimate comfort food. The secret to making them extra juicy is using a panade, a mixture of starch and liquid that acts as a binder. Here, the torn bread absorbs the milk, then is distributed throughout the meat mix to ensure the meatballs stay moist and tender when cooked. Serve this classic version over mashed potatoes or buttered egg noodles.
