Chef John's Romesco Sauce

1 . Stage

Turn on a gas stove and roast bell peppers over the open flame until soft and blackened, about 5 minutes per side. Peppers should emit steam when pressed. Transfer peppers to a bowl, cover, and let cool to room temperature.

2 . Stage

Combine oil and garlic in a skillet. Turn heat to medium and cook, stirring constantly, until garlic just starts to turn golden brown, about 3 minutes. Move garlic to a ramekin using a slotted spoon, leaving all the oil in the skillet.

3 . Stage

Toast bread in the oil until golden brown, 2 to 3 minutes.

4 . Stage

Peel peppers under running water. Cut peppers open and remove the seeds. Chop into cubes and transfer to a food processor. Add garlic, bread cubes with oil, almonds, vinegar, paprika, cayenne, and salt. Pulse on and off until sauce is well combined and reaches your desired texture.

5 . Stage

Transfer sauce to a bowl. Cover with plastic wrap and refrigerate to intensify the flavors, 8 hours to overnight.
