This butter will remain spreadable even when it has been refrigerated, so you can enjoy the taste of butter any time.
/ 250 ml salted butter
1 lb / 454 g
/ 250 ml oil
Let butter soften to room temperature.
Place in mixer bowl and beat until it is very soft and smooth.
Warm oil slightly (either in microwave, or by letting measuring cup sit in a bowl of hot water.) You don't want it to be hot- just slightly warm.
With the mixer on, slowly add the oil in a thin stream. Add it slowly enough that you don't have pools of oil on the bottom of your bowl.
Scrape down the side of the bowl occasionally until all the oil has been added.
Continue beating for a couple of minutes until the butter is smooth.
The mixture will be very soft at first. Scoop it into a container and refrigerate. It will firm up but still remain spreadable.
