When cooking, we often need soft butter at room temperature, but butter needs to be in the refrigerator, and is always hard.
The reflex is to put it in the microwave, but it ends with melted butter, which does not give the same results ...
So to have soft butter, the trick is really simple: heat a glass of water in the microwave for 1 minute.
Pour the hot water and put the hot glass over the butter.
After a few minutes under the glass, the butter will have the right consistency to butter the bread and cook!
