I enjoy konjac pasta. Yes, 0 net carbs.
For best results, rinse and drain thoroughly, and then dry it to make it more like the spaghetti, etc., that we’re used to. You dry it by sauteing or microwaving until the translucence is gone and the rinse water has evaporated.
I used to skip this step, but it does make it better, and some people are turned off by the smell and/or texture if you don’t do the drying thing.
Eleven net carbs in half a cup of ice cream? That seems like a lot. I used to make ice cream with cream, water, unflavored gelatin, sweetener, and whatever flavor I was going for. Sometimes I used flavored gelatin, which already has sweetener and flavor. Orange Jello + vanilla = Creamsicle flavor! Sorry I can’t remember the exact recipe. Anyway it was easy, with no sugar, no starch, etc.
