Sweet Onion Jam

Method

Ahi Tuna Preparation

  1. 1

    Prepare the Tuna

    Season the Ahi tuna steaks with kosher salt and crushed black peppercorns. Press the peppercorns into the surface of the tuna.

  2. 2

    Sear the Tuna

    Heat olive oil in a skillet over medium-high heat. Sear the tuna steaks for 1-2 minutes on each side for medium-rare, or to your desired doneness. Remove and let rest.

Fingerling Potatoes Preparation

  1. 3

    Roast the Potatoes

    Preheat your oven to 400°F (200°C). Toss the fingerling potatoes with olive oil, salt, and fresh rosemary. Spread them on a baking sheet and roast for 25-30 minutes until golden and tender.

Haricot Vert Preparation

  1. 4

    Blanch the Green Beans

    Bring a pot of salted water to a boil. Add the haricot vert and blanch for 2-3 minutes until bright green and tender-crisp. Drain and immediately transfer to an ice bath.

  2. 5

    Sauté the Green Beans

    In a skillet, melt butter over medium heat. Add the blanched haricot vert and sauté for 2 minutes. Season with salt and lemon juice before serving.

Frisee Salad Preparation

  1. 6

    Dress the Salad

    In a large bowl, combine frisee lettuce, olive oil, balsamic vinegar, salt, and pepper. Toss to combine and plate.

Horseradish Crema Preparation

  1. 7

    Make the Crema

    In a small bowl, mix together sour cream, prepared horseradish, and lemon juice until well combined. Refrigerate until ready to serve.

Sweet Onion Jam Preparation

  1. 8

    Cook the Onion Jam

    Slice sweet onions thinly. In a saucepan, combine onions, brown sugar, balsamic vinegar, and a pinch of salt. Cook over medium heat until the onions are caramelized and the mixture is jam-like, about 30-40 minutes.
