I knew of this dessert because I've heard of it, but my grandmother never made it so I set out on a journey to find a good recipe and wa la someone had posted a photo of Nitza Villapol's book on the page where she wrote this lucky me. (I don't feel bad not buying it because Nitza stayed in Cuba and never got a dime for what she did, so money wont go to her anyway even if I bought the book plus she's dead RIP)
About Boniato is a type of white sweet potato used in Cuban Cuisine. It has a reddish dark purple skin, and solid white flesh, when cooked the flesh becomes a pale yellow. It can go by other names like "Tropical Sweet Yam", "Tropical Sweet Potato", "Cuban White Sweet Potato"
It is not as sweet as the regular sweet potato used in the USA (which is orange fleshed) it is very starchy, and has a potato like consistency with a hint of sweetness.
The Boniato oxidizes easily so it must be peeled quickly and put in water to prevent discoloration. Also it's very perishable try to use in less than 1 week stored at room temperature.
If you cannot find "Boniato" use a white fleshed sweet potato, like a Japanese sweet potato or something of that sort.

(3)When Boniato is cooked, mash to a paste (you can use the food processor to help or do it the old fashioned). Set aside.
(4)Slowly mash in syrup to prevent lumps, bring mixture to a boil on high then lower to medium stir for about 6-8 minutes, add butter, stir well again, now remove from heat add beaten egg yolks slowly in a stream stirring fast in one direction.

P.S. For a different flavor when making the syrup use 4 cups water, 4 cups sugar, peel of 1 lime, and 1 cinnamon stick and make into a syrup, and continue recipe as directed.ALSO yes I know it's very sweet Cuban desserts are sweet, it's as sweet as marmalade, your only suppose to have a little bit, maybe like 1/4-1/2 cup after dinner to cleanse pallet from a garlic heavy Cuban dinner :)... sadly I can't help myself I had a big heaping bowl of this after dinner ha ha...
