How to Make It
Use a dehydrator or, alternatively, preheat the oven to 150° F.
Line a baking sheet with parchment paper.
In a medium pot, bring the sugar and water to a boil and simmer until the sugar dissolves. Reduce the heat to medium, add the carrots, and cook for 6 minutes, until the carrots are tender. Let the mixture cool for another 2 minutes, then drain. (Reserve and refrigerate the liquid; it can be used to rehydrate the carrots or to sweeten other dishes.)
Place the carrots in a single layer on the baking sheet. Dehydrate or dry in the oven for 8 to 10 hours, until they are completely dry and no longer feel rubbery. They should look like 1-inch-long batons. The “raisins” can be stored in an airtight container for several months. To use, rehydrate in a little warmed syrup.
The carrots take a while to dehydrate and they reduce in size significantly, so drying a larger amount at one time will be a more efficient use of oven or dehydrator space.
