Rouille is a traditional Provençal spicy garlic mayonnaise. It is usually served with bouillabaisse fish stew.
Baguette bread
1 egg yolk
100 ml olive oil
4 garlic cloves
Saffron or annatto (for color)
6 Tbsp fish stock
Salt
Pepper
Blend the bread, fish stock, and egg yolk together into a paste.
Crush the garlic and saffron or annatto, and add to the paste.
Gradually add the oil with one hand while vigorously whisking with the other, as when preparing any other mayonnaise.
Add salt and pepper to taste.
