Rouille is a rustic Provençal cousin of aioli, built from garlic, saffron, and a touch of cayenne whisked into olive oil until thick and glossy. It traditionally thickens with mashed potato or soaked bread, giving it a silkier, more rustic texture than a straight mayonnaise. Serve it floated on fish soup or spread on toasted baguette.
Ingredients
- 1 small red potato, peeled and cubed
- 4 cloves garlic, minced
- 1/4 teaspoon saffron threads
- 1 tablespoon hot water
- 1 large egg yolk
- 1/2 teaspoon cayenne pepper
- 1 tablespoon fresh lemon juice
- 3/4 cup extra-virgin olive oil
- 1 teaspoon kosher salt
- 1/4 teaspoon freshly ground black pepper
Method
-
Place the potato cubes in a small saucepan, cover with water, and bring to a boil over high heat.
-
Reduce heat and simmer the potato until fork-tender, about 10 minutes, then drain and mash until smooth. Set aside to cool slightly.
-
Steep the saffron threads in the hot water for 5 minutes to release their color and aroma.
-
In a medium bowl, whisk together the mashed potato, minced garlic, egg yolk, cayenne, lemon juice, and saffron with its soaking water until well combined.
-
Whisking constantly, drizzle in the olive oil a few drops at a time at first, then in a slow steady stream, until the mixture emulsifies and thickens like mayonnaise.
-
Season with salt and black pepper, whisking to combine. Taste and adjust lemon juice or cayenne as needed.
-
Transfer the rouille to a jar or airtight container and refrigerate at least 20 minutes before serving to let the flavors meld.
