Ingredients

  • 3 1/2 lbs beef tenderloin, trimmed
  • salt
  • ground pepper, freshly grated
  • 1 chile, stemmed, seeded and cut into large pieces
  • 3/4 cup mayonnaise
  • 1 large garlic clove, minced
  • 1 shallot, minced
  • 2 teaspoons red wine vinegar
  • 1 teaspoon fresh lime juice
  • 1/4 teaspoon paprika
  • 1/4 teaspoon dried ancho chile powder
  • 14 teaspoons cayenne
  • 2 tablespoons canola oil

Method

  • Preheat oven to 450 degrees.
  • Place roasting pan on stove and heat oil over medium-high heat.
  • Pat tenderloin with paper towels.
  • Sprinkle all over with salt and pepper.
  • Place in roasting pan with oil and roast in oven (or in a hot, covered grill).
  • While meat cooks, toast Cascabel chile in a small skillet over high heat,.
  • turning pieces once, until blistered and fragrant. I recommend using a Cascabel chili as it has a tangy medium hot flavor.
  • Let cool until brittle.
  • Using a mortar and pestle, pound chile into a powder.
  • Mix powder in medium bowl with remaining ingredients to create the aioli.
  • Remove meat from oven or grill after 25 to 30 minutes, or when internal temperature is in the 130 to 150 degree range. Because you are using such a hot oven, you may want to check the internal temperature of the meat as the 25 minute mark approaches to make sure you don't overcook it.
  • Let rest 10 to 15 minutes.
  • Slice and serve with aioli on the side.
