Ingredients

Scale

Vegetables

  • 1/2 lb jalapeño peppers (about 6 large peppers)
  • 1/2 onion, peeled and quartered
  • 2 cloves garlic, crushed and halved
  • 10 sprigs cilantro, roughly chopped

Liquids and Seasonings

  • 2/3 cup white vinegar
  • 1 cup water
  • 1 tsp sugar
  • 1 tsp salt
  • 1/2 tsp cumin
  • Oil to coat the pan (about 1-2 tbsp)

Instructions

  1. Heat the pan: Bring a cast iron pan to medium-high heat and add a splash of oil to coat the bottom, ensuring the surface is hot enough for roasting.
  2. Roast vegetables: Add the whole jalapeño peppers, quartered onion, and crushed garlic cloves to the hot pan. Roast them for about 5 minutes, turning frequently to achieve an even light browning and develop smoky flavor.
  3. Slice the peppers: Carefully remove the roasted peppers from the pan and slice them into rings, being cautious of the heat and seeds.
  4. Simmer the peppers and onions: Return the sliced jalapeños and roasted onions to the pan and add 1 cup of water. Simmer gently for about 5 minutes, stirring occasionally to soften the ingredients further and blend flavors.
  5. Add remaining seasonings: Stir in the garlic, salt, cumin, and sugar. Continue simmering for an additional 1 minute, allowing the spices to infuse the mixture.
  6. Blend the sauce: Transfer the simmered mixture into a blender. Add the roughly chopped cilantro and white vinegar. Blend until the sauce is smooth and well combined.
  7. Cool and season: Let the blended sauce cool to room temperature. Taste and adjust seasoning by adding more salt and/or cumin as preferred.
  8. Store the hot sauce: Pour the finished hot sauce into hot sauce bottles, mason jars, or your preferred container. Refrigerate to keep fresh and enhance flavors over time.

Notes

  • Roasting the jalapeños and onions adds a smoky depth that elevates the flavor of the sauce.
  • You can adjust the heat by removing some or all of the seeds from the jalapeños before blending.
  • The sauce thickens slightly as it cools; add a splash of water if you prefer a thinner consistency.
  • Store the sauce in the refrigerator and consume within 2-3 weeks for best freshness.
  • Use gloves when handling jalapeños to avoid skin irritation.
