While I was in Denver this summer, my brother Lenny was making his own spreadable butter. I just tried it myself and will definitely continue doing this! Basically... this easy step cuts about 3/4 of the cost of this food staple... instead of buying a tub of spreadable butter, I can now make my own from a couple sticks and some canola oil (although I didn't have canola... so I used a mixed seed oil).
I followed the recipe found here and plan on trying to mix in a couple herbs for a smaller batch soon. Mmmmhmmmmm!
Funny timing on seeing Lenny do this at his house - as I had a huge block of hard butter in my refrigerator that was always impossible to try and scrap away at to use. ....Problem solved. : )
