Preparing Spicy Dilis is a simple yet rewarding process. Follow these steps to make your own at home:

1. Rinse the Anchovies: Rinse the dried dilis under cold water to remove excess salt. Drain and set aside.
2. Prepare the Marinade: In a bowl, mix vinegar, soy sauce, sugar, and black pepper. Stir until the sugar dissolves.
3. Cook the Aromatics: In a pan, heat vegetable oil over medium heat. Sauté the minced garlic and sliced onion until fragrant.
4. Add the Anchovies: Toss the rinsed anchovies into the pan and stir-fry for about 3 minutes until they turn slightly golden.
5. Incorporate Spices: Add the sliced chili peppers to the anchovies and stir for an additional minute.
6. Combine with Marinade: Pour the marinade over the sautéed anchovies. Stir well to ensure all the fish is coated in the sauce.
7. Cook Together: Allow the mixture to simmer for about 5-10 minutes, allowing the flavors to meld.
8. Cool and Store: Remove from heat and let it cool. Transfer to a clean jar and cover. Let it marinate in the refrigerator for at least 2 hours, or overnight for maximum flavor.
9. Serve: Your Spicy Dilis is ready to enjoy once marinated!
