1/2 cup of heavy whipping cream sorry you have to use this if your making butter not subs.
There are two ways of doing this you can either put this in your food processor for 15- 20 minutes or less time. Or you can do this by hand constantly for 15-20 minutes. If you do this by hand put your heavy whipping cream into a small container with a lid and shake it for about 15-20 minutes and drain off the excess cream and you will have butter. Or you can put the heavy whipping cream into the food processor and let it go until it looks like butter and starts to separate from the cream. Drain off the excess cream and you have butter. You can flavor this with salt and pepper or garlic or even herbs too.
So even though its not health food its still better for you than the crap they sell in the stores and some of that stuff never goes bad so you can only imagine all the bad things they have in there to keep the shelf life forever. I hope you all have a great weekend, live , laugh and love everyone!
