The mirabelle plum, also known as the mirabelle prune (Prunus domestica var. syriaca), is the edible drupaceous fruit of the mirabelle prune tree, a cultivar of the prune tree. It is believed that the plum was cultivated from a wild fruit grown in Asia Minor.
Clafouti, sometimes spelt clafoutis, is a custard-like baked French dessert that is typically made by baking fresh fruit (traditionally cherries) and a batter, somewhat similar to pancake batter, in a baking dish.
Originally from Limousin, the dish's name comes from the occitan clafotís, from the verb clafir, meaning « to fill up » (implied: " the batter with cherries"). Clafoutis apparently spread throughout France during the 19th century.Wikipedia
