Step 1: Preparing the Beef Heart

1. Trim the beef heart: Remove any fat, connective tissue, and valves using a sharp knife.
2. Slice the heart: Depending on the cooking method, cut into steaks (1-inch thick), cubes (for stews), or thin strips (for stir-fries or skewers).
3. Rinse and soak (optional): For a milder flavor, soak the slices in cold water with a splash of vinegar for 30 minutes, then pat dry.

Step 2: Marinate (Optional, Recommended for Grilling or Pan-Searing)

1. In a bowl, whisk together vinegar, soy sauce, minced garlic, and seasonings.
2. Place beef heart slices in the marinade and let it rest for 1 hour (or overnight for deeper flavor).

Step 3: Cooking Methods
