Salsa Roja Asada: The Alchemy of Char and Stone

Overview

This video unveils the traditional method for crafting salsa roja asada, emphasizing the transformative power of charring ingredients on a comal and the unique texture created by grinding them in a volcanic molcajete. It details ingredient selection, precise roasting times, and the sequential grinding technique to achieve a foundational Mexican sauce. The process culminates with a crucial resting period to integrate flavors and optimize texture.

Ingredients

• 500 grams Roma tomatoes
• 30 grams jalapeños
• 15 grams serrano chilies
• 100 grams white onion
• 15 grams garlic
• 5 grams coarse sea salt
• 15 grams finely chopped fresh cilantro
• 15 milliliters fresh lime juice

Instructions

1. Heat a dry cast-iron skillet or comal over medium-high heat until it reaches exactly 200 degrees Celsius (400 degrees Fahrenheit).
2. Lay the tomatoes, chilies, onion, and unpeeled garlic directly onto the dry metal.
3. Remove garlic after exactly 5 minutes.
4. Sear chilies for 8 minutes, rotating them every 2 minutes until fully blistered.
5. Roast tomatoes for 12 minutes, turning them sequentially until 60 percent of their surface is blackened and the skins begin to split.
6. Once roasted, peel the papery skin off the garlic, but leave the black char on your tomatoes and chilies.
7. Place the three roasted garlic cloves into a basalt molcajete along with 5 grams (1 teaspoon) of coarse sea salt.
8. Using the tejolote, grind in firm circular motions for 2 minutes until you form a perfectly smooth, sticky paste.
9. Pinch the stems off your jalapeños and serranos, drop them into the garlic paste, and crush them firmly for 3 minutes.
10. Add the charred tomatoes one by one, gently pressing and crushing each tomato against the stone to integrate the juices into the chili paste, aiming for a rustic, chunky texture.
11. Add 15 grams (half an ounce) of finely chopped fresh cilantro.
12. Squeeze exactly 15 milliliters (1 tablespoon) of fresh lime juice over the mixture and fold it through gently with a spoon.
13. Let the molcajete sit undisturbed at room temperature (around 20 degrees Celsius/68 degrees Fahrenheit) for exactly 20 minutes before tasting.

In this video

• Traditional salsa roja asada is a foundational sauce of Mexican gastronomy, built on the alchemy of char, friction, and time.
• To build a true salsa roja, gather 500 grams of Roma tomatoes, 30 grams of jalapeños, 15 grams of serrano chilies, 100 grams of white onion, and 15 grams of garlic.
• Heat a dry cast-iron skillet or comal to exactly 200 degrees Celsius (400 degrees Fahrenheit) for the maillard reaction.
• Garlic must be removed from the hot comal after exactly 5 minutes to prevent bitter, burnt allicin compounds.
• Chilies should be seared for 8 minutes, rotating them every 2 minutes until fully blistered, while tomatoes require 12 minutes until 60 percent blackened.
• A basalt molcajete is used to grind the three roasted garlic cloves with 5 grams (1 teaspoon) of coarse sea salt for 2 minutes into a smooth, sticky paste.
• After creating the garlic paste, chilies are crushed firmly for 3 minutes, and charred tomatoes are gently pressed one by one to achieve a rustic, chunky texture.
• Adding 15 grams (half an ounce) of finely chopped fresh cilantro and 15 milliliters (1 tablespoon) of fresh lime juice brightens the roasted earthiness.
• The salsa requires a 20-minute resting period at room temperature (around 20 degrees Celsius/68 degrees Fahrenheit) to allow pectins to thicken and flavors to integrate.
• If salsa becomes overwhelmingly spicy, add 15 milliliters (1 tablespoon) of distilled white vinegar instead of sugar, which would ruin the savory profile.

Frequently asked questions

What ingredients are needed for a traditional salsa roja asada?

The base includes 500 grams of Roma tomatoes, 30 grams of jalapeños, 15 grams of serrano chilies, 100 grams of white onion, and 15 grams of garlic. Coarse sea salt, fresh cilantro, and lime juice are also essential.

How hot should the comal be for roasting salsa ingredients?

A dry cast-iron skillet or traditional comal should be heated over medium-high heat until it reaches exactly 200 degrees Celsius, or 400 degrees Fahrenheit.

What are the roasting times for the various salsa ingredients?

Garlic is removed after 5 minutes, chilies are seared for 8 minutes, and tomatoes are roasted for 12 minutes, with a 60 percent blackened surface.

Why is a 20-minute resting period important for salsa?

This resting phase allows the cellular walls of the tomatoes to release pectin, naturally thickening the ambient juices, and lets the sharp acetic bite of the lime juice mellow and marry with the alkaline ash from the charred skins.

How can I adjust the spiciness of salsa without compromising flavor?

If the salsa is too spicy, add 15 milliliters, or 1 tablespoon, of distilled white vinegar. Never add sugar, as it masks the heat but ruins the savory profile.
