I had some whipping cream in my fridge for the past month or so, had been planning on making alfredo with it but never got around to it. Noticed it was about to expire, so decided to open it up and made some home-made icecream.
Just did equal parts heavy cream (1 cup container) and 2% milk. Added a little vanilla extract, about a teaspoon of salt, and then threw in sugar until it tasted good, something like 5 heaping tablespoons ish didn't really measure it, probably about half a cup if I had to guess.
Whisked it a bunch, then stuck it in the freezer, whisked it rapidly again every half hour or so until it was frozen after about 2 hours... was super easy and came out really good, lots of recipes online call for heating up the cream and whatnot, screw that... I used 1 dish, 1 whisk, 1 spoon and it came out great.
Maybe about 5 minutes of actual "work" to make an amazing desert.
