📝 About This Recipe

Hailing from the sun-drenched coast of Marseille, Rouille is the essential, fiery companion to a traditional Bouillabaisse. This velvety, rust-colored emulsion balances the heat of cayenne pepper with the floral luxury of saffron and the sharp bite of fresh garlic. It is a sophisticated condiment that transforms simple seafood dishes into an authentic Provencal feast.

🥗 Ingredients

The Aromatics

  • 4 pieces Garlic cloves (large, germ removed and roughly chopped)
  • 1/2 teaspoon Saffron threads (high quality, crushed)
  • 1/2 teaspoon Sea salt (flaky or fine)
  • 1/4 teaspoon Cayenne pepper (adjust for desired heat)
  • 1/4 teaspoon Smoked paprika (for depth of color)

The Binding Base

  • 1 large Egg yolk (at room temperature)
  • 1 slice White bread (crusts removed, torn into small bits)
  • 2 tablespoons Fish stock or warm water (to soak the bread)
  • 1 teaspoon Lemon juice (freshly squeezed)
  • 1/2 teaspoon Dijon mustard (acts as a stabilizer)

The Emulsion Oils

  • 1/2 cup Extra virgin olive oil (fruity, high quality)
  • 1/2 cup Grapeseed or vegetable oil (neutral flavor to balance the olive oil)

👨‍🍳 Instructions

  1. 1

    Place the torn bread bits in a small bowl and drizzle with the warm fish stock or water. Let it sit for 5 minutes until soft and pasty.

  2. 2

    In a mortar and pestle, combine the chopped garlic and sea salt. Grind vigorously until a smooth, translucent paste forms.

  3. 3

    Add the crushed saffron threads, cayenne pepper, and smoked paprika to the garlic paste. Continue to grind until the spices are fully integrated and the color is a vibrant orange.

  4. 4

    Squeeze any excess liquid from the soaked bread and add the bread paste to the mortar. Work it into the garlic-spice mixture until completely uniform.

  5. 5

    Transfer this flavorful base to a medium-sized glass bowl. Whisk in the room-temperature egg yolk, Dijon mustard, and lemon juice until smooth.

  6. 6

    Combine the olive oil and neutral oil in a measuring cup with a spout for easy pouring.

  7. 7

    Secure your bowl by placing it on a damp kitchen towel to prevent it from sliding while you whisk with one hand.

  8. 8

    Begin adding the oil mixture drop by drop, whisking constantly and vigorously. This slow start is crucial for a stable emulsion.

  9. 9

    Once the sauce begins to thicken and look glossy, you can increase the flow of oil to a very thin, steady stream.

  10. 10

    Continue whisking until all the oil is incorporated and the sauce has the consistency of a thick, spreadable mayonnaise.

  11. 11

    Taste the Rouille. If it needs more acidity, add a drop more lemon juice; if it needs more heat, add a pinch of cayenne.

  12. 12

    Cover and refrigerate for at least 30 minutes before serving to allow the saffron and garlic flavors to bloom and meld together.

💡 Chef's Tips

Use room temperature egg yolks to ensure the emulsion forms easily and doesn't break. If the sauce breaks (separates), whisk a fresh egg yolk in a clean bowl and slowly whisk the broken sauce into it. For the most authentic texture, use a mortar and pestle for the garlic paste rather than a food processor. Always remove the 'germ' (the green sprout) from the center of the garlic to avoid a bitter, overly harsh aftertaste. Store in an airtight container in the fridge for up to 3 days, but do not freeze.

🍽️ Serving Suggestions

Slather generously onto toasted baguette croutons and float them in a steaming bowl of Bouillabaisse or fish stew. Serve as a dip alongside chilled poached shrimp or grilled calamari. Use as a bold spread for a Mediterranean-style roasted vegetable sandwich. Pair with a crisp, chilled Provencal Rosé or a dry Vermentino to cut through the richness of the garlic and oil.
