De Buyer Extendable Stainless Steel Rectangle to 40 x 21cm


The De Buyer extendable stainless-steel rectangle is just what patissiers and bakers need for pristine opera cakes or entremets in any size from 21.5 x 11.5cm up to 40 x 21cm. So there’s no need for a teetering pile of different sized frames filling up your cupboards.

The rectangle has a smooth sliding action, so you can easily adjust the size to your needs. The inner surface is smooth and flat, for the perfect finish on cakes and tarts.

Use the extendable rectangle with a flat baking sheet as a mould for homemade fudge or marshmallows. Or even use for chocolate ganache to make square or rectangular truffles. Line with pastry film or parchment paper for even smoother sides – and cut down on washing up!

The frame is made of durable stainless steel. It’s slightly flexible for easy release, and the rectangle always returns to its original shape.
