Erythritol is my favorite. Monk fruit is very sweet. They say xylitol is laxative like and stevia is the bitter tasting one. I use a lot of erythritol in baking.
I think the erythritol I bought has a weird, mediciney after taste. Maybe it’s the brand, but it says “pure.”
I made some sugar free, flourless choc chip cookies last weekend with xylitol and stevia sweetened chocolate chips. Used almond flour instead, butter and coconut oil. Real eggs. They were out of this world.
