Why This Recipe Works

For a sweet and tangy burger topping, we start by roasting cherry tomatoes along with shallot and ground cinnamon. Once the tomatoes soften and brown in the oven, they are ready to be processed into a quick “jam” by mixing in store-bought orange marmalade. The result is a sweet-tart, lightly spiced mixture that pairs nicely with the earthy burgers.

Before You Begin

Line the baking sheet with foil for easy cleanup.

Instructions

Adjust oven rack to middle position and heat oven to 425 degrees. Toss tomatoes, shallot, oil, salt, and cinnamon together in bowl. Transfer to aluminum foil–lined rimmed baking sheet and roast until edges of tomatoes are well browned, 15 to 20 minutes. Let cool slightly; transfer tomato mixture to food processor. Add marmalade and process until smooth, about 10 seconds.
