Prep time: 20 minutes
Total time: 2 hours
1. Heat the butter in a medium skillet over medium. Add 700 grams of the apples and cook until tender and soft, about 10 minutes. Set a timer as to not over cook.
2. Transfer the apples and any butter left in the skillet, along with the remaining apples and the juice, to a Vitamix and purée until smooth. Pass mixture through a fine mesh chinois.
3. Add the sugar, stabilizer, citric acid, and xanthum gum to the apple mixture and whisk together. Transfer the mixture back to the Vitamix and blend the entire mixture (in batches) on low speed for 3 minutes, to marry the ingredients, yet not add too much air.
4. Spin the sorbet according to your specific ice cream machine settings.
