How to Make the Ultimate Umami-Bomb Vegetarian Demi-Glace
1 large jalapeño, seeded and coarsely chopped
1 large garlic clove
1 small shallot, coarsely chopped
1 1/2 tablespoons capers
3 oil-packed anchovies, drained
3 tablespoons extra-virgin olive oil
3/4 pound gemelli
Two 3 1/2-ounce cans of Italian tuna in olive oil, drained
15 cherry tomatoes, halved
Kosher salt and freshly ground pepper
8 large basil leaves, coarsely chopped
Bring a large pot of salted water to a boil. In a food processor, finely chop the jalapeño with the garlic, shallot, capers and anchovies. In a large, deep skillet, heat the olive oil. Add the jalapeño mixture and cook over moderate heat until it begins to turn light golden, about 3 minutes. Remove from the heat.
Cook the gemelli in the boiling water until al dente. Drain the pasta, reserving 1/3 cup of the cooking water. Add the gemelli and the cooking water to the skillet and toss with the jalapeño mixture over low heat until evenly coated. Add the tuna and tomatoes and cook until heated through. Season with salt and pepper, stir in the basil and serve.
