Chef John's Romesco Sauce

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.

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.

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

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.

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