Cashew Crema and Smoky Red Pepper Sauce

Put the cashews in a medium bowl and pour over enough water to cover the cashews by 1 inch. Soak for at least 2 hours or as long as overnight. Drain and rinse well.

In a food processor, combine the cashews, ¼ teaspoon of the salt, and ¼ cup cold water and process until smooth, about 2 minutes. Using a rubber spatula, scrape down the sides. Add another ¼ cup water and process until creamy and smooth, 3 to 4 minutes more. If you prefer a thinner consistency, adjust the water accordingly. Taste and add the remaining salt as needed. 

Use immediately or store in an airtight container in the refrigerator for up to 4 days.

Preheat the broiler and raise the oven rack to 5 or 6 inches below the heat source.

Put the bell peppers on a baking sheet and drizzle evenly with the olive oil. Sprinkle ½ teaspoon of salt and the black pepper over them. Broil until charred, about 15 minutes. Flip the peppers over and broil, flipping every 5 minutes until completely charred, 10 to 15 minutes more. Remove the peppers from the oven and let cool. 

Remove and discard the charred skin, seeds, and stems and transfer the flesh from the peppers to a blender or food processor. Add the mayonnaise, vinegar, the remaining 1 teaspoon salt, the hot sauce, and the cayenne and blend until smooth. 

Serve immediately, or store in an airtight container in the refrigerator for up to 3 days.
