Ingredients

  • 1/2 lb. Serrano peppers (approx. 18-20)
  • 1 Habanero pepper (optional)
  • 1/4 onion
  • 1 garlic clove
  • 1/2 cup white vinegar
  • 1/4 cup water
  • juice of 1 lime
  • freshly cracked black pepper
  • 1/2 teaspoon salt
  • 1 teaspoon Mexican oregano
  • 1/4 teaspoon cumin (optional)
  • 8-10 cilantro sprigs

Instructions

  • Give the Serranos a good rinse and de-stem them.  Be sure to wash your hands after handling them. More tips on handling hot chiles.
  • Saute a roughly chopped 1/4 onion and 1 whole, peeled garlic clove in a glug of oil over medium heat.
  • Once the onion is browning you can add 1 teaspoon Mexican oregano, some freshly cracked black pepper, and 1/4 teaspoon cumin (optional). Briefly cook until fragrant and then add the de-stemmed Serranos, 1/2 cup white vinegar, 1/4 cup water, and 1/2 teaspoon salt. You can optionally add a rinsed and de-stemmed Habanero pepper. Bring to a simmer and then add everything to a blender.
  • Add 8-10 sprigs cilantro and the juice of 1 lime to the blender. Combine well or to your desired consistency. I usually leave it a bit chunky but you can always blend it thinner.
  • Add mixture to two 5 oz. bottles or a small Mason jar. Store in the fridge where it will keep for weeks at a time.

Notes

These are hot chiles so use caution when handling them!   Be sure not to touch your eyes or nose after chopping them up.  More tips on handling hot chiles.
It's best to use a non-reactive pan for this recipe -- I've mistakenly used my cast iron pan in the past and the acidity will eat away some of the pan's seasoning.
