Salsa Roja

The secret to a robust salsa roja isn't just the ingredients; it's the char. You are looking to push the vegetables right to the edge of burnt, as that carbonized skin provides the depth that raw salsa lacks.

Before you start

Control the heat at the source

The heat of your salsa is determined entirely by how many seeds you leave in the serrano or jalapeño peppers. Adjust accordingly before blending.

  • cast-iron skillet
  • blender or food processor
  • tongs
Ingredients

What goes in.

  • 4roma tomatoes
  • 1/2white onion, peeled and cut into thick slabs
  • 2serrano chiles, stems removed
  • 2 clovesgarlic, unpeeled
  • 1/4 cupfresh cilantro, roughly chopped
  • 1 tspsea salt
  • 1 tbspfresh lime juice
The key technique

Don't fear the black spots

Blackened skin on tomatoes and peppers is flavor. Keep them in the pan until the skins are deeply charred and peeling away, as this adds a smoke note that binds the ingredients together.

Step by step

The method.

  1. Roast the vegetables

    Place tomatoes, onion slabs, chiles, and unpeeled garlic in a dry cast-iron skillet over medium-high heat. Let them sit undisturbed until the bottoms are charred, then flip.

  2. Peel and prep

    Once everything is charred and softened, remove from heat. Peel the garlic cloves and discard the skins. Keep the charred skins on the tomatoes and peppers.

  3. Pulse

    Place the roasted vegetables, salt, and cilantro into the blender. Pulse 4-5 times. Stop while there are still visible chunks; a smooth sauce lacks the necessary mouthfeel.

  4. Season

    Transfer to a bowl, stir in the lime juice, and taste for salt. Let the salsa sit at room temperature for 15 minutes before serving so the flavors settle.

Variations

Other turns to take.

Salsa Morita

Add 2 dried morita chiles to the pan for a deeper, smokier fruitiness.

Creamy Style

Add half an avocado to the blender for a richer texture.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Use a cast-iron skillet; the uneven heat helps create better char patterns than a stainless pan.

Tip

If the salsa is too thick, add a tablespoon of water, never oil.

Tip

The salsa improves after an hour, as the salt draws the juices out of the tomatoes.

Questions

The ones that keep coming up.

Should I remove the charred skin?

No. The charred bits are essential for the smoky profile of a true salsa roja.

Can I use canned tomatoes?

You can, but they will not char properly. Fresh, firm roma tomatoes are necessary for the best texture.
