Why I love this recipe: fresh corn cobs and kernels are steeped in the custard mixture, and the cobs are then pureed into the custard, imparting the deepest sweet corn flavor to this ice cream. Sour cream adds extra richness and helps temper the sweetness, and a tart, blueberry, raspberry, bay leaf infused jam is swirled into the freshly churned ice cream, adding bursts of fruity tart August flavor.
