Browning butter is not hard, it is a fairly quick process and you should just concentrate on doing this once started as it is a very fine line between brown and burnt butter, so do not leave the stove unattended. It only takes 6-7 min. Here's how: 1. Place a pan over medium heat. 2. Keep stirring the butter - it is important to keep it moving all the time. Once it has melted, it will begin to foam mainly around the edges. 3. Continue to stir for about 7 minutes until the butter turns golden brown. The milk solids turn brown and oh, the smell - deliciously nutty, toasty, buttery smell. * This is the point the butter needs to be removed from the heat and ideally is to pour it into another cool heatproof pan or bowl to stop it from cooking any further. This is a very important step as this is the point where the butter will turn to a burnt point. This is it! Brown butter is done! It is a really nice addition to this brownie giving it a really nice nutty flavour. Top tip: Use a light-colored pan so you can easily see and judge the color of the butter and decide when done.
