Hi - I have a mobile mini donut business. The donuts are cake donuts that are fried, then topped (variety of guests’ choice) and served hot to guests. Trying to figure out an easy/food truck friendly glaze recipe that can stick (stick better) to hot donuts. I can’t “dip” ’the tops. Instead, the glaze is applied from a squeeze bottle. I wonder if there’s an additive I can add to the glaze (basically just water, confectioners sugar and vanilla) that can help it not thin and drip off so fast as they’re served. Thoughts?
