Literally, it's just a small carton of heavy whipping cream stired with a handmixer until it turns from a liquid to a foam. Then, you add a small can of sweetened condensed milk, 3 tsp of vanilla extract, and a pinch of salt. Mix that together.
And BOOM!
That's basic vanilla ice cream. Just freeze for 8 hours.
You can mix anything in before freezing to make any ice cream. I put in a while sleeve of double stuff oreos, salted peanuts, honey, and caramel in one batch. It was amazing. In the batch I just made, I did a sleeve of oreos, an entire bag of minature reese peanut butter cups, sweetened coconut shavings, and white chocolate chips. Can't wait to try that one.
Holy shit, I was lead to believe by every piece of media that you need an ice cream maker. What a load of shit!
