Blueberry oil

First, take the butter (75 g) out of the refrigerator to soften a little. This will make it easier to mix with the blueberries. Then place the butter in a bowl.

Add the fresh blueberries (30 g) to the butter. Using an electric mixer, thoroughly mix the butter and blueberries until you achieve a homogeneous mass.

You can adjust the degree of mixing depending on whether you want to keep some blueberry pieces or achieve a smoother texture.
