I took 2 cups of cold heavy cream (straight from the fridge) in a bowl and used an electric hand mixer on it at it's slowest setting and watched it undergo its various transmutations:
- After about 4 minutes the mixture started to get a little thicker and started to resemble a flat whipped cream, with many air bubbles forming on the surface.
- After 6-7 minutes, it seemed like a full bodied whipped cream, having expanded in volume some.
- At 8-9 minutes it suddenly started to harden quickly and turned into a cottage cheese consistency within seconds. I thought I was done, but there was no liquid separating from it so I kept going.
- A few more minutes and it started to yellow, and liquid started forming in the bottom. I kept at it for another minute until it seemed like no more milk was separating from the butter.
- I then poured the chunky liquid mess into a cheese cloth of a bowl and squeezed it to get most of the liquid out. I then saved this liquid and used it for pancakes.
- I then took some ice water in a bowl and rinsed the bar of butter that I formed in it to get the residual milk off.
