House-Made Salsa Roja

This is a foundational condiment that prioritizes charred heat over raw acidity. It gains its character from the scorched skin of the vegetables, which adds a smoky undertone that permeates the final blend.

The importance of the char

Do not pull the vegetables out of the oven too early. The blackened, papery bits of tomato skin are essential for the final flavor profile.

Ingredients

What goes in.

  • 1.5 lbRoma tomatoes, halved lengthwise
  • 1/2white onion, cut into thick wedges

  • 2garlic cloves, skins left on
  • 1/2 cupfresh cilantro, roughly chopped
  • 1 tbspfresh lime juice
  • 1 tspkosher salt
The key technique

Controlled Scorching

Position your oven rack in the highest slot. Watch the vegetables closely; the goal is deep charring without turning the interiors into mush.

Step by step

The method.

  1. Broil the vegetables

    Place tomatoes, onion, peppers, and garlic on a baking sheet. Broil on high for 8–10 minutes, flipping once, until skins are blistered and darkened.

  2. Prepare the aromatics

    Remove the garlic from its charred skin. Discard any overly burnt pepper stems if they didn't come off during roasting.

  3. Pulse the blend

    Add roasted vegetables, salt, and lime juice to the blender. Pulse 5 to 7 times. You want a coarse texture, not a thin puree.

  4. Fold in finishings

    Add the fresh cilantro. Pulse twice more just to incorporate. Taste and adjust salt if necessary.

Variations

Other turns to take.

Smoky Variation

Add half a teaspoon of ground cumin or one rehydrated chipotle pepper in adobo before blending.

Creamy Texture

Add half a ripe avocado to the blender to emulsify the salsa into a thicker, richer consistency.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Use Roma tomatoes because they contain less water, preventing the salsa from turning watery after sitting.

Tip

Always salt to taste after blending; the heat of the peppers can mask the perception of salt.

Tip

Let the salsa sit at room temperature for 30 minutes before serving to allow the flavors to marry.

Questions

The ones that keep coming up.

Why leave the skins on the tomatoes?

The skin holds the charred flavor. Removing it strips the salsa of its primary source of smokiness.

How long does it stay fresh?

Keep it in a sealed glass jar in the refrigerator for up to four days.
