Place heavy cream in food processor or blender. Hit blend and watch your appliance do the work. You will see the mixture changes in both consistency and color over about 2-3 minutes.
Continue to mix until cream separates into butter and butterfat. Drain off butterfat. Discard or reserve for other recipes like White Chocolate and Raspberry Pancakes.
Add 1/2 cup ice water and continue to blend for 30 seconds. Drain off water. Add additional 1/2 cup ice water and repeat. Drain.
Remove from food processor or blender and fold in cheese salt by hand. Mix well or else you will get a mouth full of salt at some point. Add other flavors as well- fresh herbs, citrus zest, dried fruit bits or other spices.
Refrigerate until ready to use in any recipe that requires butter!
