Main Ingredients

Method

Preparation

  1. 1

    Roasting the Sweet Potatoes

    Preheat your oven to 400°F (200°C). Wash the Japanese sweet potatoes thoroughly and pierce them with a fork several times. Place them on a baking sheet lined with parchment paper and roast for 45-60 minutes, or until they are tender and cooked through.

  2. 2

    Making the Brown Butter

    While the sweet potatoes are roasting, melt the unsalted butter in a saucepan over medium heat. Continue cooking, swirling the pan occasionally, until the butter turns golden brown and has a nutty aroma. Be careful not to burn it. Once browned, remove from heat and set aside.

  3. 3

    Preparing the Nori Vinaigrette

    In a small bowl, finely chop the nori sheets and mix them with rice vinegar, soy sauce, and a pinch of salt and pepper. Stir well to combine and set aside.

Assembly

  1. 4

    Serving the Dish

    Once the sweet potatoes are roasted, remove them from the oven and let them cool slightly. Cut them open and fluff the insides with a fork. Drizzle a generous amount of brown butter over each sweet potato, followed by a dollop of crème fraîche. Finally, drizzle the nori vinaigrette on top and season with additional salt and pepper to taste.
