Decant the liquid. If there is no liquid, then the butter you bought did not contain too much of it and it evaporated during the melting process.
Your melted butter is ready. You only need to implement final details in order to be able to use it in the future.
Return the pot on the cooker and melt it again. Once you’ve done it, empty it to storage jars using sieve. This is done because butter contains other ingredients. They will stay on the bottom of the pot and it is important that, when you empty the butter to storage, that sediment is not emptied in the jar too. You can also use muslin cloth.
