Use the "big" holes on the box grater. Some people prefer the rice made with the medium holes, I find it too small for cauli flower, but make your experiments and decide what works best for you!
Grate each piece
Use a towel to squeeze out some of the moist. This is optional when the rice feels a bit wet, but very recommended for avoiding soggy rice
Just to make sure, this is what we mean by squeezing out the moist!
You can then put some garlic, onion, olive oil and stock powder (buillon) on a pan and saute the rice. Make sure you do it in small batches to get the perfect results! if you put a lot of rice it will get soggy even if you removed the moist
Uncooked is freezer friendly! although it will only last for about 1-2 months. Note that when it is just done it works much better. Cooked rice will last around 5 days in the fridge.
Notes
This recipe is very good for those who want to reduce their calorie intake
It can be done using a food processor. I personally think it is worth just using the grater, as it takes about 5 minutes to grate a big cauliflower! no big deal :)
Cook it in "small portioins" otherwise it will get soggy!
Although most people like cutting the cauliflower, I personally just grate the whole piece. It makes less mess, at least in my experience!
