Aji Rojo Baby Back Ribs with Peruvian Dry Rub

Great ribs don't need a bottle of sweet, smoky American BBQ sauce. They need patience, a good rub, and something with real heat and character in the glaze. Aji rojo handles the last two.

Rocoto pepper — the base of our rojo sauce — has been used in Peruvian cooking for thousands of years. It's fruit-forward with serious heat, and it caramelizes beautifully under high heat. On baby back ribs, it creates a lacquered, deeply flavored crust that you won't get from any store-bought BBQ sauce.

The method here is low-and-slow in the oven first, then a quick finish on the grill. You get fall-off-the-bone texture with the char and smoke of the grill. Both are necessary. Neither is optional.

Aji Rojo Baby Back Ribs Recipe

Serves: 4
Time: 3.5 hours total (30 min active)
Difficulty: Medium — low effort, long time

For the Dry Rub

• 2 racks baby back ribs (about 4–5 lbs total)
• 2 tablespoons Aji Rojo sauce
• 1 tablespoon smoked paprika
• 1 tablespoon brown sugar
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon cumin
• 1½ teaspoons salt
• 1 teaspoon black pepper

For the Rojo Glaze

• 3 tablespoons Aji Rojo sauce
• 1 tablespoon honey
• 1 tablespoon apple cider vinegar
• 1 tablespoon soy sauce

Instructions

1. Prep the ribs. Remove the membrane from the back of each rack — slide a butter knife under the membrane at one end, grab it with a paper towel, and pull. It comes off in one piece. This is not optional.
2. Make the rub. Combine all dry rub ingredients including the rojo sauce into a paste. It will be thick. Coat both sides of each rack generously. For best results, wrap in plastic and refrigerate overnight. Minimum: 2 hours.
3. Oven low and slow. Preheat oven to 275°F. Place racks bone-side down on a foil-lined baking sheet. Cover tightly with foil. Bake 2.5 to 3 hours until the meat is tender and pulling away from the bones.
4. Make the glaze. Whisk rojo, honey, vinegar, and soy sauce together. Set aside.
5. Finish on the grill. Get your grill to medium-high. Remove ribs from the oven, unwrap, and place on the grill. Brush with glaze. Grill 4–5 minutes per side, brushing again each time you flip, until the glaze is caramelized and slightly charred at the edges.
6. Rest and cut. Rest 5 minutes. Cut between bones and serve with extra rojo on the side.

Why Rojo Works on Ribs

American BBQ sauce is built on tomato, molasses, and smoke. It's sweet and familiar. Rojo is built on rocoto pepper, which is fruity and fiery in a completely different way. The heat isn't just spicy — it has dimension. Combined with honey in the glaze, it creates a sweet-heat balance that's more complex than anything in the standard BBQ playbook.

Peru doesn't have a BBQ culture the way the American South does. But it has rocoto. And on ribs, that turns out to be the same thing.

Tips

• Don't rush the oven step. 2.5 hours minimum. 3 hours is better. The collagen needs time to break down.
• Brush the glaze in the last 10 minutes only. Earlier and the sugar burns before the ribs are done.
• Rest before cutting. Always.
• No grill? Broil on high for 5–6 minutes, watching closely, to get the caramelization.
