Jack in the Box Taco Sauce is a tangy, mildly spicy condiment served in packets with their tacos. Made from tomato puree, vinegar, spices, and a touch of sweetness, it offers hints of chili pepper, garlic, and onion. Its smooth texture and approachable heat make it a popular addition not only to tacos, but also to other menu items, adding a flavorful and familiar kick to every bite.
