I used to listen to an herbalist on the radio; she talked about making "better butter".
You mix softened butter in the blender with a good oil - equal amounts. It's better for your cholesterol.
Way easier to spread, too, but it's not for baking.
I used to make it with canola oil for some things, and olive oil for others, but now I just make the olive oil version; it's healthier. Tastes very nice on morning toast or English muffins. It goes pretty fast around here. When I realized I was making it once a week, I doubled the recipe.
