Financiers are small almond cakes made with brown butter and shaped like gold bars, hence the name. It is one of the few bakes where the mould is half the identity, and this tray gives you six with the right elongated shape and straight sides.
The tray is from Gobel's Obsidian range with a non-stick coating, so the cakes release when they should and not a minute later. It measures 380 x 180 mm and fits a standard oven without negotiation. Gobel is a French maker of moulds for pastry chefs, and for home bakers who like to pretend to be one.
