Method

Preparing the Orange Gel

  1. 1

    In a bowl, combine mayonnaise, harissa paste, minced garlic clove, and lemon juice. Whisk until smooth and well blended.

  2. 4

    Chill the Aioli

    Cover and refrigerate the harissa aioli for at least 15 minutes to allow the flavors to meld.

Preparing the Tuna and Vegetables

  1. 5

    Slice the Tuna

    Using a sharp knife, slice the yellowfin tuna into thin sashimi-style slices. Set aside.

  2. 6

    Prepare the Avocado

    Halve the avocado, remove the pit, and slice it into thin pieces.

  3. 7

    Slice the Cucumber

    Thinly slice the cucumber into rounds.

  4. 8

    Prepare the Piquillo Peppers

    Drain the piquillo peppers from the jar and set aside for plating.

    On a serving plate, artistically arrange the slices of yellowfin tuna, avocado, cucumber, and piquillo peppers.

    Using a spoon or squeeze bottle, drizzle the orange gel around the plate.

  3. 11

    Finish with Harissa Aioli
