During my recent trip down to New York for my Bulletproof Coach training program, I had to improvise making my daily dose of Bulletproof Coffee. There was no blender, so I stuck some Kerrygold Unsalted butter I bought from Whole Foods straight into this flask and shook it like a shake weight. The things we do for our morning BPC.
I took this at Olifants Private Game Reserve, South Africa. It was a frosty morning when we noticed a young pride of lions walking about 50 meters from our vehicle.
