I think this is it- just Aioli with cayenne
Chili Pepper Aioli
Alan Wong's Restaurant
In a blender, combine the mustard, garlic, egg, egg yolk and lemon and puree. With the machine running, slowly add the olive oil until incorporated. If the mixture becomes too thick, thin with a little water. Season with salt and pepper. Keep refrigerated.
For Chili Pepper Aioli, add 1/8 teaspoon cayenne to 1/4 cup aioli.
