A little belated followup - I tried it, and I feel it was way too thin, even after adding corn starch. I would cut that water way down. Maybe even add as needed after initial blending. Not sure why that is, don't remember it being that thin.

Oh thanks, that might save my first batch! It may take me a few days to try it, but I’ll definitely report back.

NP... Maybe it's due to the recipe being made so variable. The water might help with the oatmeal variant.
