Rouille

Rouille  is a red garlicky sauce (pronounced roo-EE, rouïo in Provençal)

Traditionally it is an accompaniment for bouillabaisse, but also nice with grilled seafood. (or w/anything you care to add it to) It will keep in the  fridge either the same day or the next.  If the rouille is stiff, thin it with a few drops of boiling water. Here are several recipes
Marseille Recipe
2 chili peppers
4 cloves garlic
1 cup olive oil
1 egg yolk
1 handful bread
1 Tbsp rock salt
 Trim, de-seed and chop finely the peppers, in a mortar, crush the peppers, garlic, rock salt and olive oil
(1 teaspoon) together to obtain a thick paste. Crumble the bread, moisten it with hot water (or the bubbling broth if you're preparing bouillabaisse), and press it into a tight lump, squeezing out the liquid.
Add the bread lump to the paste and beat, adding olive oil, until you've raised a smooth sauce. If the sauce tends to separate, add another tight lump of bread and hot broth, and keep beating.
Nice Recipe
2 tsp cayenne pepper
3 cloves garlic
1 cup olive oil

Add the egg yolks, and beat into a mayonnaise while adding about a half-cup of olive oil.
