There's a not-so-quiet revolution going on in kitchens around the country.

A machine is promising to change the way you cook and eat.

There's no sugar-coating its price though, and the little marvel will set you back almost two grand.

Carmella is a Thermomix convert. She's had her machine for a couple of years, and swears by it.

"Initially the cost really was a shock, but then if you look at it over the long-term, and the amount of cooking I do, it ends up saving you money."

Whipping up a minestrone in minutes, she says "it does suit my lifestyle, and the fact that I like to eat healthy, and I like to have preservative, additive free food. This enables me to do that without having to stand in the kitchen for hours."

The Thermomix story is as remarkable as the device itself.

Grace Mazur from Balcatta introduced Thermomix to Australia ten years ago, after seeing one while visiting her native Poland.

On her return she lobbied the German company to award her the rights in Australia. Last year she turned over $51 million in sales - that's 73 machines sold every day.

So what is a Thermomix? Well according to the company it's a kitchen on your bench - doing the job of a host of other kitchen appliances. It’s a steamer, blender, grinder, mixer, bread maker, and the list goes on.

The Thermomix cooks as well as chops, blends and even weighs the ingredients as you put them in.

Mazur says you can whip up a three course meal in minutes.

A strawberry sorbet can be ready within 90 seconds, at a cost of just 40 cents a serve.

To make pumpkin soup, onion cooks for one and a half minutes. It's stirred as it cooks, and takes just fifteen minutes, at a cost of 44 cents a serve.

To cap off the meal is a mushroom risotto, which is great to eat, but usually tedious to make.

Mushrooms, wine, and homemade stock go in, and that's it. The Thermomix cooks and stirs for sixteen minutes, you add some parmesan cheese, and it's done for $1.00 per serve.

The hefty price tag might put of some would-be cooks, yet so far 50,000 people have bought a Thermomix in Australia, and that number is sure to rise.
