Sprinkle powdered gelatin over 1/4 cup cool almond milk. Stir and set it aside for at least 5 minutes to bloom while you mix the base.
In a sauce pan, whisk together remaining 2 cups almond milk, brown allulose, pumpkin puree, vanilla extract, pumpkin pie spice, and salt.
Heat this mixture on medium heat while whisking to a simmer.
Remove from heat. Pour into blender. Add bloomed gelatin-almond milk mixture. Blend for 1 minute.
Cool sorbet base to room temperature. Taste and adjust sweetness to your liking.
Place into your ice cream machine (click HERE to find the one I LOVE)and watch the magic happen within 15 minutes or according to your ice cream maker’s directions. Freeze until set.
NOTE: if your pumpkin pie sorbet hardens too much, let it thaw 15 minutes before serving.
