Ilcos-Style Spiced Vinegar

• 2 cups [475 ml] palm vinegar or rice vinegar (see Tip)
• 15 whole

In a sterilized, airtight jar or other nonreactive container with a lid, combine the vinegar, chiles, galangal, ginger, garlic, and peppercorns. Let rest at room temperature for at least 3 days before using. Transfer to a long-neck bottle with a speed pourer for easier use. Sinamak will keep for several months on the countertop or in your pantry and will deepen in flavor over time.
