Slow Roasted Tomato Jam

Slow roasted tomato jam is rich, sweet and what you need all over your crostini. A sweet, savory jam ripe with caramelized cherry tomatoes and roasted garlic, this warm tomato jam is great base for avocado toast, a spread for turkey sandwich or equally at home on a charcuterie board. It'll be your jam.
