Rocoto Base for Ceviche and Seafood Dishes

A smooth, strained rocoto base (a spicy Peruvian red chile) for use in ceviches, tiraditos, and seafood preparations. Made by triple-blanching rocoto to reduce heat intensity, sautéing with onion and garlic, adding white vinegar for brightness, blending with water, and straining to a silky red sauce. Unlike the ají amarillo base, this one does NOT require flambéing.

Ingredients

40 ml Vegetable oil (Added cold to pan before heating)
60 g White onion, minced (Minced fine)
5 g Garlic, minced (Minced fine)
250 g Rocoto (Peruvian red hot pepper), deseeded (Seeds and veins removed; blanched 3 times from cold water to reduce heat intensity)
Salt (Added while sautéing)
White vinegar (Added during sautéing for brightness and acidity)
100 ml Cold filtered or mineral water (Added to blender to help liquefy the mixture)

Steps

1

Prepare the rocoto: remove seeds and veins from 250g of rocoto. Place in a saucepan and cover with cold water. Bring to a boil, drain, and repeat 3 times total — always starting from cold water. This triple blanching significantly reduces the extreme heat of rocoto while preserving its fruity flavor. Chop the blanched rocoto as finely as possible.

Tip: Always start blanching from cold water, not hot. The gradual temperature change is what makes the blanching effective.

Heat 40ml oil in a pan over medium heat. Add 60g onion and 5g minced garlic. Cook until the onion softens and takes on a light color. Add 1 tsp salt.

~5 min
3

Add the finely chopped blanched rocoto to the pan. Stir and cook together (rehogamos). Add 1 tsp white vinegar — this adds brightness and a subtle acidity that complements the rocoto's fruitiness. Note: unlike the ají amarillo base, do NOT flambe the rocoto — it does not benefit from the smoky treatment.

Tip: The white vinegar is a differentiator in this base vs the ají amarillo base. It balances the rocoto's intensity without masking it.

Turn off the heat. Transfer the mixture to a blender. Add 100ml cold filtered or mineral water. Blend at high speed until completely smooth.

Strain the blended mixture through a fine sieve, pressing gently. Discard solids. The result is a smooth, vibrant red rocoto base — ready to use in ceviches, tiraditos, and leche de tigre preparations.

Tip: Store refrigerated in a sealed container for up to 5 days. Can also be used as a base for rocoto relleno and other Peruvian dishes.

Cultural Context

Rocoto (Capsicum pubescens) is a uniquely Andean chile pepper with thick flesh, black seeds, and intense heat. Unlike most chiles, it thrives at altitude and has been cultivated in the Andes for thousands of years. In Peruvian cevicherías, rocoto base is used to add a bold, fruity heat to ceviches and leche de tigre. Victor Heredia presents this as a companion to the ají amarillo base — the two sauces cover the full spectrum of Peruvian seafood flavor profiles and are produced using the same blanching-and-straining method for consistency.
