Serrano Hot Sauce

This serrano pepper hot sauce uses fresh peppers and tomatillos from the garden. It's bright, spicy and flavorful.
Prep Time 15 minutes
Cook Time 25 minutes
Total Time 40 minutes
Servings 15 oz

Ingredients

  • 1/2 lb. serrano peppers stemmed (approximately 20)
  • 1 cup onion chopped
  • 4 cloves garlic
  • 2 tablespoons olive oil for charring
  • 1 cup water
  • 2 tablespoons fresh ginger peeled and chopped
  • 1 tomatillo husked and chopped
  • 1 cup white vinegar plus extra to thin the sauce
  • 1 tablespoon sugar
  • 1 teaspoon salt
  • 3 tablespoons fresh lime juice
  • 1 teaspoon smoked paprika optional, for smoky flavor

Instructions

Preparation

  • Bring a cast iron skillet to medium high heat. Add the olive oil and char the serrano peppers, garlic, and onion for about 5-10 minutes, turning the ingredients occasionally to blacken evenly.
  • Once charred, transfer the peppers, garlic, and onion to a saucepan. Add 1 cup of water and bring to a boil. Reduce the heat and simmer lightly for 10-15 minutes, until peppers and onions are softened.
  • Add the chopped ginger, tomatillo, and sugar to the saucepan. Continue to simmer for an additional 10-15 minutes until the ginger is tender. Most of the liquid should be evaporated.
  • Remove the saucepan from heat and let the mixture cool slightly. Then, transfer the mixture to a high-powered blender. Add 1 cup of white vinegar, salt, lime juice, and smoked paprika.
  • Blend the mixture until smooth. If the sauce is too thick, you can add a bit more white vinegar to reach your desired consistency.
  • Taste the hot sauce and adjust the seasoning as needed, adding more salt, sugar, or lime juice to balance the flavors.
  • Once satisfied with the taste and consistency, strain the hot sauce through a fine mesh sieve to remove any solids. This step is optional, but I recommend it for a more splashy sauce.
  • Transfer the strained hot sauce into sterilized bottles or jars. Allow it to cool completely before sealing tightly.
  • Store the hot sauce in the refrigerator for up to 6 months.

Notes

  • Feel free to swap out some of the serranos for other peppers, but try to keep the weight about the same. For example, use 1/4 lb serranos and 1/4 lb bell peppers for a less-spicy version of the hot sauce.
  • Do not slice the peppers before charring them - this will cause capsaicin to release into the air, potentially causing breathing discomfort.
  • For less bitterness, remove the seeds from the peppers after charring.
