Pour the heavy cream into your food processor, electric whisker, or mixer.

Whip the cream for approximately 4 mins. After approximately 2 minutes into the 4 minutes, you will see the mixture whip over and start to thicken, continue to whip.

Once it has separated, pour in the ice-cold water. This will help facilitate the separation, mix for another minute.

Place a cheesecloth or sieve over a bowl and pour in your mixture. The liquid you see is buttermilk and is great to cook with... save if you prefer.

Squeeze or press the butter to remove ALL of the buttermilk. If you leave the buttermilk in it, it will make your butter wet.

Mix in your salt. (Now is the perfect time to mix in any flavors you desire. Adding fresh garlic to the butter is great on steaks).

Press into a butter dish or your favorite container.

Store in the fridge and enjoy the taste of REAL butter.
