If that’s your only objection, I’d recommend checking your local grocery store for pre-riced cauliflower. That’s what I used, and it did save a lot of time and hassle. As I understand it, it’s becoming more and more common to find in stores. Enough so that the rice industry is getting miffed.
Cauliflower Grilled Cheese
Trader Joe’s has packages of fresh and frozen organic cauliflower rice for a decent price.
None of the stores nearby me carry riced cauliflower. I used the same method as you did the first time I made these, with equal annoyance. After having watched Headbangers Kitchens risotto video, I realised that I had been doing it wrong. He used the grating-disc in his food processor, not the knife. This was SO much easier! If you can’t get the readymade riced cauliflower, I recommend trying the cheese grater
Here’s another method of ricing cauliflower. Place chunks if it in a blender, fill blender with water, buzz away.
This does a very good job of creating tiny cauliflower particles. Unfortunately, it also leaves you the task of removing all that moisture. A fine mesh strainer is the initial step. Afer that I usually pour the damp mass onto 2 layers of tea towels and press hard.
