I have been cooking Knorr Sides for a long time. I followed the directions and after the ten minute timer went off, the spiral pasta was still tough, had not cooked to tender at all. So, I let it cook another 5 minutes, and it was still too tough to eat. My husband threw his out after taking a sample taste. It's very disappointing and I am going to contact the manufacturer with a formal complaint regarding this product. They need to change the pasta out to something else and stop using spiral.
