I used Kerrygold Irish butter from grassfed normal cows. Put it in hot strong black coffee. It was great. I don’t know what you need a blender for; I just put it in the cup. Gave me energy all morning. Kerrygold costs twice as much as the garbage butter I could get at the supermarket ($3.69/half pound) but it’s less trouble than making it myself, and sometimes time is money. Tastes so good my son was just eating it plain.
I guess I should have went further with my posts.
I was making the recipe for “Bulletproof coffee”.
Coffee, grass Fed butter, MCT oil (derivative of coconut oil).
Put in blender and blend.
(The blending helps the oil blend in instead of sitting on top)
I used my Nutribullet, but was worried the hot coffee would melt the plastic.
I then used a small hand blender, but grew tired of the whole ordeal.
