1-First, prepare your ingredients by combining the ground beef, ground pork, bread crumbs, finely minced onion, milk, eggs, Worcestershire sauce, salt, and pepper in a large bowl. Mix thoroughly but gently to keep the meatballs from becoming too dense, which helps them stay juicy during cooking. For dietary variations, swap in alternatives as needed before shaping.

2-Second, shape the mixture into evenly sized meatballs, about 1 inch in diameter, to ensure uniform cooking.

3-Third, fry them in vegetable shortening over medium heat or bake them in the oven until they reach 165°F (74°C) for food safety.

4-Fourth, transfer the cooked meatballs to your crockpot.

5-Fifth, in a separate bowl, mix the chili sauce and grape jelly until well blended, then pour it over the meatballs in the crockpot.

6-Sixth, cover and cook on low for 6-8 hours or on high for 3-4 hours, allowing the flavors to meld.

7-Finally, serve them hot, perhaps over rice or with veggies for a complete meal.
