Cruffin

A cruffin is croissant dough baked in a muffin tin: a strip of laminated, butter-layered pastry rolled into a tight spiral, stood upright in a deep cup and baked so it rises into a tall cylinder with a flaky, ridged exterior and an open, pull-apart centre, then rolled in sugar and usually filled from the top with pastry cream, curd, jam or ganache. The name is a straightforward blend of croissant and muffin and the pastry is a child of the 2010s: Kate Reid's Lune Croissanterie in Melbourne is widely credited with the first ones around 2013, and Mr. Holmes Bakehouse in San Francisco made the word famous, trademarked it in the United States and built queues around it a year later. It belongs with the cronut and the crookie in the family of hybrid viennoiserie that bakeries use to sell croissant dough at a higher margin, and like them it is only as good as the dough underneath the idea.
