Half the peppers and remove all seeds and membranes. Press them flat with your hand and lay them on a foil lined, rimmed baking sheet. Place the garlic cloves on the baking sheet.

Set the oven on broil and raise the rack to the upper position. Broil the red peppers and garlic for 15 minutes.

Once the skin has blackened, remove from the oven and place in a large zip bag to steam. (10 minutes)

Preheat a large pot to medium heat. Add the oil, thyme, bay leaves, and onions. Cook for 10 minutes, until onions are soft.

Add the broth, hot sauce, salt and pepper. Squeeze the garlic cloves out of their skins and add to the pot.

Bring to a simmer and cook for 15 minutes.

Remove from heat and carefully blend with an immersion blender or in a regular blender until smooth.

Stir in the rice vinegar.
