📝 About This Recipe

Tracing its roots back to the Aztec empire, Pipian Rojo is a sophisticated Mexican masterpiece known for its deep earthy tones and velvety texture. Unlike a traditional chocolate-based mole, this 'mole de semillas' relies on toasted pumpkin seeds and sesame for its signature nutty richness, balanced by the smoky heat of dried chiles. It is a vibrant, rust-colored celebration of pre-Hispanic flavors that transforms simple proteins into a feast for the senses.

🥗 Ingredients

The Seed and Nut Base

  • 1 1/2 cups Pumpkin Seeds (Pepitas) (raw, unsalted)
  • 1/2 cup Sesame Seeds (unroasted)
  • 1/4 cup Peanuts (raw or dry roasted, unsalted)

The Chile Blend

  • 4 pieces Ancho Chiles (dried, stems and seeds removed)
  • 3 pieces Guajillo Chiles (dried, stems and seeds removed)
  • 2-3 pieces Chiles de Árbol (optional, for extra heat)

Aromatics and Spices

  • 3 pieces Roma Tomatoes (halved)
  • 1/2 piece White Onion (thickly sliced)
  • 4 pieces Garlic Cloves (peeled)
  • 2 pieces Whole Cloves
  • 4 pieces Whole Black Peppercorns
  • 1/2 inch Mexican Cinnamon Stick (also known as Canela)

Liquid and Fat

  • 4-5 cups Chicken or Vegetable Stock (high quality, warm)
  • 3 tablespoons Lard or Vegetable Oil (lard is more traditional for flavor)
  • 1 teaspoon Salt (or to taste)

👨‍🍳 Instructions

  1. 1

    Heat a large skillet or comal over medium heat. Toast the pumpkin seeds, stirring constantly, until they begin to puff up and pop (about 3-5 minutes). Be careful not to burn them; remove immediately and set aside.

  2. 2

    In the same skillet, toast the sesame seeds and peanuts until golden and fragrant (about 2 minutes). Add them to the bowl with the pumpkin seeds.

  3. 3

    Briefly toast the dried chiles (Ancho, Guajillo, and Árbol) for 30-60 seconds per side until they become aromatic and slightly pliable. Do not let them blacken or they will turn bitter.

  4. 4

    Place the toasted chiles in a bowl of hot water and let them soak for 15-20 minutes until completely softened.

  5. 5

    While chiles soak, char the tomatoes, onion, and garlic in the dry skillet until they have blackened spots and the onion is translucent.

  6. 6

    Toast the cloves, peppercorns, and cinnamon stick for 1 minute until fragrant, then grind them into a fine powder using a spice grinder or mortar and pestle.

  7. 7

    In a high-powered blender, combine the toasted seeds, nuts, charred vegetables, ground spices, and the soaked chiles (discard the soaking water). Add 2 cups of stock.

  8. 8

    Blend on high until the mixture is incredibly smooth. If the motor struggles, add another cup of stock. The goal is a thick, silky puree.

  9. 9

    Heat the lard or oil in a heavy-bottomed pot or cazuela over medium heat. Once shimmering, carefully pour in the blended sauce—it may splatter as it hits the fat.

  10. 10

    Reduce heat to low. Stir in the remaining stock until you reach the consistency of heavy cream.

  11. 11

    Simmer the sauce gently for 25-30 minutes, stirring frequently to prevent the seeds from sticking to the bottom. The sauce will darken and the oil will begin to bead on the surface.

  12. 12

    Season with salt to taste. If the sauce is too thick, whisk in a little more warm stock before serving.

💡 Chef's Tips

Always toast your seeds and spices in small batches to ensure even browning and prevent burning. For the smoothest texture possible, pass the blended sauce through a fine-mesh strainer before frying it in the pot. If the sauce tastes too 'nutty' or heavy, a tiny splash of apple cider vinegar or lime juice at the end can brighten the flavors. Don't skip the 'frying' step in the pot; this 'seasons' the sauce and creates the deep, cooked-through flavor essential to a good Pipian. Leftovers freeze beautifully for up to 3 months—just reheat slowly and whisk in a little water to loosen.

🍽️ Serving Suggestions

Serve generously over roasted chicken thighs or poached turkey breast. Use as a rich sauce for cheese or chicken enchiladas, topped with pickled red onions. Pair with a side of Mexican red rice and warm corn tortillas to soak up every drop. Accompany with a crisp, cold Lager or a tart Hibiscus (Jamaica) iced tea to cut through the richness. For a vegetarian option, pour over roasted cauliflower steaks or grilled chayote squash.
