This traditional Yemeni relish is served throughout the year at lunch or dinner, as an accompaniment to roasted meats and vegetables and as a spread for falafel and other sandwiches.
Pulse jalapeno and garlic in a food processor until finely chopped. Add herbs, season with salt and pepper, and pulse until finely chopped. With motor running, slowly add oil, processing until mixture resembles a loose paste. Serve in a bowl, with matzo.
