Work in progress, but here’s my current recipe, which is pretty good:
In a bowl, whisk the following dry ingredients:
1/3 cup polydextrose or VitaFiber
2 Tbsp erythritol
2 Tbsp xylitol
1/8 tsp xanthan gum
1/4 cup cocoa powder (I used Hershey’s special dark)
Add 1 bottle chilled Soylent 2.0, 1 tsp vanilla flavor, 4 drops Sweetz-free brand sucralose drops (comparable to one “packet” of sugar-free sweetener) and whisk with powder until smooth. Put in ice cream mixer.
Nutrition info: The xylitol adds somewhere in the ballpark of 12g of carbs. The cocoa powder adds some fat. The rest of the ingredients are calorie free, so the nutritional value isn’t too far off from what Soylent contains. (Be aware that this recipe has a LOT of fiber, and some people are sensitive to xylitol, so eat sparingly the first time until you know how your stomach handles it).
