I don't know about you, but my family and I go to the State Fair every year pretty much for the food. I know, that sounds appalling, but it's a once a year thing. Our arteries have a year to recover. One of the treats that we can't leave without is pineapple whip ice cream. The state fair is the only place we've found it. My mom used to Jones for it until she found a recipe that is as close as you can get to the real deal.
The coolest part is that it's made of only three ingredients: pineapple juice (one 46oz can), sugar (2 cups), and half & half (2 cups OR 1 cup heavy cream and 1 cup milk).
Pour the pineapple-y goodness into your ice cream maker of choice and churn according to the directions of your specific machine. Ours churned for about 35 minutes.
