We purchased a 4 lb bag of Purely Frozen Organic Broccoli Florets to try from Costco. The 4-pound bag came in four 1-pound bags. We cooked one of the bags of broccoli following the microwave instructions. The instructions stated to microwave on HIGH for 5-6 minutes, and we went with 5 minutes.
The taste of the broccoli was fine... just like regular broccoli. However, the texture of the broccoli was a little on the soft and mushy side, and there was a lot of excess moisture from being frozen. The next time we had some of this broccoli, we tried microwaving it for 4 minutes, and it was still a little frozen... so perhaps the perfect cook time in our microwave is about 4 1/2 minutes.
