Secret to Tender Beef Skewers with Pineapple Marinade

Process the garlic, onion, and pineapple in a food processor until a paste forms. Use moderate amounts of these ingredients to avoid significantly altering the texture of the meat.

Add the soy sauce, vinegar, oil, a little salt, and annatto powder to the processed paste.

Pour the seasoning over the meat (1kg) and mix well to coat all the pieces.

Let the meat marinate for a maximum of one hour, as the pineapple can drastically alter the texture if left for too long.

Grill the skewers in an air fryer to test the tenderness and flavor, if a charcoal grill is unavailable.
