Add the whipping cream and sugar to a medium mixing bowl (if using a hand mixer) or the bowl of a stand mixer (if using a stand mixer, use the whisk attachment).
Mix, checking often by stopping the mixer and lifting the whisk up. If a stiff peak remains in the bowl, the whipped cream is done. If soft peaks that gradually sink back in result, it needs mixed more. Be careful not to over mix or you'll have butter.
Once stiff peaks result, whisk in the vanilla and salt just until mixed (should only take a few seconds).
Transfer to an airtight container and store in the refrigerator.
Jar Method
Add all ingredients plus 2 clean marbles to a quart size jar. Screw on the lid and tighten.
Shake, shake, shake! Get the whole family involved. Check every 5 minutes or so to see if the cream is stiff and ready to use. When the clacking of the marbles slows down, it's getting closer to completion.
