Cuban Boniatillo (sweet Potato Paste Dessert)

READY IN: 2hrs 45mins
Recipe by Jellyqueen

This very sweet little dessert is made from the Cuban sweet potato called a boniato. There really is no substitution, but if you are feeling brave a white sweet potato might be OK. You can find boniato in Latin grocery stores. This is really sweet, and is served in small doses. We like it after a garlicy meal, such as Cuban Roast Pork and Mojo Crillio, served with little cups of strong espresso. This is not a typical America dessert – it’s not chocolate cake, not a hot fudge sundae – so be ready for something new - its an adventure!
