I bought a box from Amazon last month. I noticed irregular shapes of what looked like plastic pieces, but as I took some pieces and rubbed them with my fingertips they appeared to have broken down very easily. They felt like fat particles. Perhaps it’s the packaging and the exposure to cold in the warehouse. At least I’m hoping that’s what it is. I’ve used it for baking since and it makes a great flour replacement. I made pumpkin spice muffins with nuts that were delicious.
