Sweet potatoes glazed in piloncillo syrup are a traditional Mexican candy sold by street vendors. This naturally sweet, family-friendly treat has been a beloved confection for generations.
Wash and peel the sweet potatoes, then slice each into thick rounds for even cooking.
In a large pot over medium heat, combine water, piloncillo, cinnamon stick, and cloves; stir occasionally as the piloncillo melts.
Add the sweet potato slices to the syrup and increase heat to bring to a gentle simmer.
Reduce heat to low; cover and cook for 45–60 minutes, turning the sweet potatoes every 15 minutes to ensure even syrup absorption and prevent burning.
Once the sweet potatoes are tender and well-glazed, remove the lid and let simmer uncovered for 10–15 minutes more until the syrup thickens to your liking.
