This neat video from ChefSteps shows an interesting frozen dessert experiment for geek chefs.
A simple technique for making amazing soft serve at home, no fancy gadgets required.
Here's what you will need: some dry ice, and your trusty stand mixer. Never worked with dry ice? You can often buy some, cheaply, at your local supermarket or at a big box store like Walmart or Sam's Club. From there you just need to crush it up and slowly incorporate it into your ice cream base, and within moments you'll wind up with a soft, delightful treat you can transfer to a piping bag and squeeze into cones for your friends and family. Make sure to stock up on sprinkles—we have a feeling this is going to be a big soft-serve summer at your house.
