Remove stems and seeds from the dried chilies. Soak in hot water for 15 minutes until softened.
Drain and blend the chilies with ½ cup fresh water until smooth.
In a small saucepan over medium heat, combine the chili puree, rice vinegar, honey, garlic, ginger, chili flakes, and salt. Stir well and bring to a gentle simmer.
Let it cook for 5–6 minutes, stirring occasionally.
In a small bowl, mix the cornstarch with 2 tablespoons water to make a slurry.
Slowly stir the slurry into the sauce and simmer for another 1–2 minutes, until slightly thickened.
Remove from heat and let cool completely—the sauce will continue to thicken as it cools.
Transfer to a glass jar and store in the refrigerator for up to 2 weeks.
Soaking Chilies: Soak dried chilies in hot water until fully softened, this ensures a smooth, blend-able texture and deeper flavor.
Blending Tip: For a smoother sauce, strain the blended chili mixture through a fine mesh sieve before simmering.
Honey Caution: Add honey before thickening, not after, it helps integrate the sweetness evenly as the sauce reduces.
Control the Heat: Use fewer red chili flakes or milder dried chilies if you want a gentler sauce. For more heat, leave in a few seeds or use spicier varieties like Thai or arbol.
Sauce Thickness: The sauce thickens more as it cools, aim for a slightly runnier texture while it's hot.
Storage Container: Use a clean glass jar with a tight-fitting lid to keep the sauce fresh and avoid flavor transfer.
