A couple days ago I whipped up my first batch of cultured raw cheeze (Russel Jame's video) and it's been sitting on the counter draining for the last two days as he says. However, this morning I noticed it had a TERRIBLE rancid smell. Is this what "cultured" means? It smells like chopped veggies and banana left enclosed in the sun for a couple months. Would you presume it's safe to eat? It's made of almonds, cashews, water, and probiotics.
