Use lean meat to keep meatballs from becoming greasy. Don’t overwork the mixture to ensure tenderness. Brown the meatballs well for extra flavor and texture. Adjust sweetness of the sauce to preference. Meatballs and sauce can be made ahead and reheated gently. Fresh or frozen cranberries both work well. Gluten-free breadcrumbs can be used for a gluten-free option. Variations include using ground chicken or turkey, adding jalapeños or hot sauce, experimenting with herbs, or swapping sweeteners.
