A smegma preserve, commonly eaten at breakfast. Most people spread it on bread. It's proven to be pretty healthy and a great source of calcium.
Smegmarmalade is made of smegma recolted on "smegma trees". If you want to produce some, please be sure that the smegma is well ripe, or your smegmarmalade would have an acid, piss-like taste.
A scientist : the slice always fall on the smegmarmalade side*
A mother to her child : Do not eat smegmarmalade at the spoon!
