just wondering...can i just adda box of pistachio pudding and some Lorann oil to WASC??Do I need to add any more liquid to compensate?

Sounds like it would work. When I change up the WASC recipe, I use milk instead of water, add the flavoring, for the full recipe I add one cup of the nuts, (they contain the oil in them). I've honestly never added the pudding though. I changed the WASC for Italian cream and it worked really good as far as texture and taste.
