Boil the sweet potato in plain water for 15 minutes, until very soft. Drain well and mash until smooth, with no lumps.

Put the sugar, 250 ml water, cinnamon stick, cloves and lime peel in a pan. Simmer for 10 minutes to a light syrup. Remove the spices and peel.

Stir the mash into the syrup. Cook over a low heat for 10 minutes, stirring, until thick like soft porridge.
10 min - 4
Beat the egg yolks in a bowl. Stir in a ladle of the hot mixture, then tip it all back into the pan. Cook for 3 minutes, stirring constantly and not letting it boil.
3 min - 5
Stir in the sherry, then spoon into small glasses or bowls. Cool, chill for at least 2 hours and dust with cinnamon.
