Potato Confit with Vegan Sauce Gribiche is the ultimate french comfort food. We created a composed dish by pairing the potatoes it with vegan sauce gribiche, garlic, and cornichons encircled with baby mustard greens. Sauce gribiche is a classic french sauce traditionally made from hard-boiled eggs. Some would say it’s reminiscent of an egg salad. This recipe really hits a home run with the combination of black salt, mustard and getting the textures just right. We’ve paired it with a traditional potato confit and the two together are luscious and satisfying.
