What’s the deal with brown butter? I keep seeing it in recipes and on menus.

Achieved by heating butter until the water evaporates and the milk solids caramelise, brown butter (or beurre noisette) can enhance the flavour of all the good things – cookies, cakes, pasta, pork chops. “It can be a beautiful thing,” agrees baker Lily Jones, of Lily Vanilli in east London, who recently launched an initiative across the capital to get birthday cakes to those who would otherwise go without. “It has a subtle, nutty, toffee caramel flavour that brings extra sweetness and richness.”
You’ll need a heavy-based pan and some good-quality butter cut into pieces. (“Better-quality butter equals better-tasting brown butter,” Jones insists.) As the butter melts, swirl the pan to prevent the milk solids from caramelising too quickly – “It’s ready when clear [separated] and with a nutty aroma.” Easy enough, but you’ll need to exercise patience (and not to use too high a heat), because butter can burn in the blink of an eye, says Mike Davies, chef/director of the Camberwell Arms in south London. “Over a medium heat, it will take five to 10 minutes, but just keep an eye on it,” he advises. “And remember, being a fat, butter retains heat, so it will continue cooking [once off the heat] for some time.” You’re looking for a deep golden colour before pulling the pan off the stove – “Go past that point,” Davies says, “and we’re getting into more considered territory where, for example, you might want a deeper brown butter and so would be after a more chestnut colour.” (You could, he adds, go even further with, for example, Rick Stein’s skate and black butter, but “you’re then getting slightly different flavour notes and more complex, bitter element”.)
