Cauliflower "rice" replaces the Arborio rice of traditional risotto without losing any of the richness or smoothness of regular risotto. A nice healthy side or main attraction for those that love carbs but don't want to eat them every day!
Wash and thoroughly dry cauliflower, remove all greens and roughly chop the florets.
In three batches, pulse the cauliflower pieces about 10-12 times until the “pearls” are of even size like rice grains and there are no large chunks remaining.
Transfer each batch of chopped cauliflower to a clean, dry bowl and set aside until all three batches are processed. If you have any large pieces of cauliflower left in the food processor, set them aside after each batch is finished and process all of the larger pieces at the end into the “rice” grains.
You can make this ahead. Just put dry paper towel on top of the bowl and refrigerate for a day. Don’t cover with plastic wrap or a lid or the “rice” will get soggy. You should have about 8 cups of “rice”.
When ready to make the "risotto", in a large saucepan over medium high heat, add the oil and 1 tablespoon of the butter. When the butter is just melted, add the shallots, porcini mushrooms and wild mushrooms and sauté until shallots become translucent, about 3 minutes. Raise the heat to high and stirring constantly, heat the mixture until the mushrooms start to brown.
Quickly stir in the remaining 2 tablespoons of butter and the Parmesan cheese. Taste and adjust seasoning with salt and pepper if desired. Add the truffle oil if you are using it.
