Place butter in a heavy bottomed saucepan. You can brown as much butter as you like
Brown the butter on the stove, stirring often, until it is brown and toasty
Pour the butter into a bowl and stir often until the butter starts to thicken and cool
Once it has started to thicken, transfer to jars and store in the fridge
Stirring the butter as it cools means the butter will stay homogeneous and not separate out
