Authentic vegetarian tacos become reality with canned jackfruit. This large tropical fruit is deceptively meat-like in texture, with a sweet, impressionable flavor. It takes on a warm, smoky taco taste in this recipe. Grill it. Shred it. And pile it into tortillas to be topped with onion, cilantro, sour cream and the upfront heat of a Cider Pepper Syrup.
