No low-carb website is completely without a rice-like substance called "cauli-rice" or "cauliflower rice".
I've got it, right here.
However, even made with pure cauliflower, it's still got about 4 grams of net carbs, per serving. It's also "all cauliflower", which means it's got the taste and texture of cauliflower (doing an amazing impersonation of rice, but still).
Miracle Rice or "Shirataki" Rice is a very low carbohydrate Japanese rice substitute made from the Devil's Tongue Yam (also known as the Elephant Yam or Konjac Yam). The end result is a product which is all but carb and calorie free. It's also gluten free, soy free and sugar free. It's made primarily of fiber, which the body doesn't absorb. In the end, they are very small little "pearls", more along the lines of an Israeli Couscous, in terms of shape and texture, than "rice", but ... it definitely does a fine job of being "rice", too!
Probably my personal favorite way to make "rice" is to combine cauli-rice with miracle rice. In my mind, I get some of the nutrient benefits of the cauliflower. I also get the flavor
(which I DO like), in addition to some textural contrasts. The miracle rice "stretches" the carbs, allowing me to have a slightly larger portion with my fried rice, curry, jambalaya, what-have-you.
Miracle Rice can be found online fairly easily. You can also find it in many grocery stores, as well as Asian supermarkets.
The end result isn't "rice". You can't make sushi with it, but ... it's about as much like rice as anything I've tried ... short of rice! I've fooled MANY people with it. It's ... rice!
