This is a variation of Ottolenghi's Easter Buns! Truly a fun recipe with lots of flavors. However, what i've noticed with some recipes is that they call for certain baking tin or ingredients that are not so easy to come by, like mixed-peel in this case. I've went ahead and made some changes for the average baker with average baking supplies at home can make. With these modifications, they are more of a chocolate bun with a citrus kick to it.
