Boil sugar, water and cloves together for 5 minutes.
Cool, then add sherry.
While syrup cools, arrange cake slices on a large round platter. Arrange like
flower petals, their ends meeting toward the center, leaving a 3-inch diameter hole
in the center. Between cake slices arrange long segments of peaches.
Slightly heat yolks, pour a little syrup over them, and stir. Empty into remaining
syrup and stir over medium heat until mixture coats a spoon (about 5 minutes).
