Method

Crispy Cauliflower Preparation

  1. 1

    Prepare the Breading Station

    Set up three shallow dishes: one with flour, one with beaten eggs, and one with a mixture of panko breadcrumbs, grated Parmesan, garlic powder, salt, and black pepper.

  2. 2

    Coat Cauliflower

    Dip each cauliflower floret first in the flour, then in the egg, and finally coat it with the panko-Parmesan mixture. Ensure they are well-coated.

  3. 3

    Fry the Cauliflower

    Heat oil in a deep skillet over medium heat. Fry the cauliflower in batches until golden and crispy, about 4-5 minutes per side. Drain on paper towels.

Mushroom Conserva Preparation

  1. 4

    Sauté the Mushrooms

    In a skillet, heat olive oil over medium heat. Add the minced garlic and sauté until fragrant. Add the mixed mushrooms, thyme, salt, and black pepper. Cook until mushrooms are tender and golden, about 10 minutes.

Pickled Onion Preparation

  1. 5

    Pickle the Onions

    In a bowl, combine sliced red onion, apple cider vinegar, sugar, and salt. Allow to sit for at least 30 minutes to pickle.

Tomato Jam Preparation

  1. 6

    Cook the Tomato Jam

    In a saucepan, combine diced tomatoes, sugar, lemon juice, and salt. Cook over medium heat until thickened, about 15 minutes. Let cool.

Kosho Aioli Preparation

  1. 7

    Mix the Aioli

    In a bowl, combine mayonnaise, yuzu kosho, and lemon juice. Mix until smooth.

Sandwich Assembly

  1. 8

    Assemble the Sandwich

    Slice the ciabatta rolls in half. Spread a layer of kosho aioli on the bottom half. Add a layer of lettuce, followed by the crispy cauliflower, mushroom conserva, pickled onion, and a spoonful of tomato jam. Top with the other half of the ciabatta and serve.
