Frequently Asked Questions  

Can You Make Cauliflower Rice from Frozen Florets?

Yes! Cook the cauliflower florets according to the packaging, either using the microwave to steam or stovetop until softened but not soggy.

Then pop it into a food processor and pulse it until it reaches the desired rice-like texture.

This should not take a lot of time but it will vary depending on the texture of the cooked cauliflower so for best results, pulse a couple of times then check before proceeding.
