📝 About This Recipe

This deep, dark, and mysterious salsa is a powerhouse of flavor, characterized by the intense smokiness of oil-fried Chiles Pasilla and Chiles de Árbol. Unlike fresh salsas, Salsa Negra (Black Salsa) offers a rich, nutty profile with a sophisticated bitterness that is balanced by toasted garlic and tangy vinegar. It is a versatile pantry staple that adds an elegant, umami-rich heat to everything from street tacos to high-end roasted meats.

🥗 Ingredients

The Dried Chiles

  • 10 pieces Pasilla Chiles (stems removed, wiped clean with a damp cloth)
  • 15-20 pieces Chile de Árbol (stems removed; adjust for desired heat level)

Aromatics & Nuts

  • 8 cloves Garlic (peeled and left whole)
  • 1/2 piece White Onion (cut into thick wedges)
  • 1/4 cup Raw Peanuts (unsalted)
  • 2 tablespoons Sesame Seeds (raw)

Frying & Blending

  • 1 cup Vegetable Oil (or any neutral oil like grapeseed)
  • 2 tablespoons Apple Cider Vinegar (provides essential acidity)
  • 1 teaspoon Piloncillo or Brown Sugar (to balance the bitterness)
  • 1.5 teaspoons Sea Salt (adjust to taste)
  • 5 pieces Whole Black Peppercorns (crushed)

👨‍🍳 Instructions

  1. 1

    Heat the vegetable oil in a large, heavy-bottomed skillet or Dutch oven over medium-low heat. You want the oil shimmering but not smoking.

  2. 2

    Add the whole garlic cloves and onion wedges to the oil. Fry them slowly until they are deeply golden brown and softened, about 5-7 minutes. Remove with a slotted spoon and set aside.

  3. 3

    In the same oil, add the peanuts and sesame seeds. Fry for 2-3 minutes until the seeds are golden and the peanuts smell toasted. Remove with a fine-mesh strainer and set aside.

  4. 4

    Now, work with the chiles. Start with the Pasilla chiles. Fry them in batches for about 30-45 seconds. They will puff up and change color slightly. Do not let them burn or they will become overly bitter.

  5. 5

    Add the Chiles de Árbol to the oil. These fry very quickly—usually 15-20 seconds. Remove them the moment they turn a deep, dark red.

  6. 6

    Turn off the heat and allow the oil to cool for at least 10 minutes. This is a crucial safety step before blending.

  7. 7

    Place the fried chiles, garlic, onions, peanuts, and sesame seeds into a high-speed blender.

  8. 8

    Pour the cooled frying oil over the ingredients in the blender. This oil is now infused with incredible toasted chile flavor.

  9. 9

    Add the apple cider vinegar, piloncillo (or brown sugar), sea salt, and peppercorns.

  10. 10

    Pulse the blender several times to break down the large pieces, then blend on high for 1-2 minutes until the sauce is completely smooth and looks like dark obsidian glass.

  11. 11

    Taste the salsa. It should be smoky, spicy, and savory. If it feels too thick, you can add a tablespoon of water or more oil, but it should be a thick, spoonable paste.

  12. 12

    Transfer to a clean glass jar. Let it sit for at least an hour before serving to allow the flavors to meld perfectly.

💡 Chef's Tips

Always wipe your dried chiles with a damp cloth to remove dust before frying. Watch the chiles like a hawk; the difference between 'perfectly toasted' and 'burnt' is only a matter of seconds. If the salsa is too spicy, add an extra teaspoon of sugar or more roasted garlic to mellow the heat. This salsa is oil-based, meaning it acts as a preserve; it will stay fresh in the refrigerator for up to 3 weeks. For a chunkier texture, pulse the nuts and seeds at the very end rather than blending them into the base.

🍽️ Serving Suggestions

Drizzle over grilled octopus or shrimp for an instant smoky elevation. Serve as a condiment for Tacos de Carne Asada with plenty of fresh lime. Stir a spoonful into a bowl of Ramen or chicken soup for a Mexican-Asian fusion kick. Use as a marinade for thick-cut pork chops before hitting the grill. Pair with a cold Mexican lager or a smoky Mezcal Negroni to complement the roasted notes.
