You need to freeze your mixing bowl first, and the longer you let it freeze for, the better this will turn out. Give it at least an hour in the freezer.
Next, add in heavy cream to your bowl and whisk it until you see stiff peaks start to form. This will take a few minutes of whisking.
Add in the condensed milk, but don’t mix it too much.
Add in Mountain Dew and food colouring. Once again, don’t over mix.
Store your ice cream in the freezer in a freezer-safe storage container. Let it rest there for 4-6 hours.
