1. Cut the thickest stems off the cauliflower and save them for soup. Chop or slice the cauliflower florets and pulse in a food processor until they look like rice or couscous. Don't overdo it or you will end up with mush.

2. Heat the oil in a fry pan, add the mustard seeds, green chilli and cinnamon sticks and cook for 30 seconds.

3. Add the cauliflower, tossing well to coat and let it pan-roast for one minute. Add the curry powder, turmeric, stock or water, sea salt and sugar and cook, tossing occasionally, for three minutes or until the water has evaporated and the cauliflower is tender.

4. Add spring onions, toss well, scatter with almonds or cashews and serve.

Tip: The blitzed cauliflower can get a bit whiffy if you store it before cooking.

Los Angeles chef Ben Ford - who just happens to be actor Harrison Ford's son - says he was working on a lamb dish with chef Govind Armstrong at his restaurant Chadwick in 1998, when he came up with the concept of "ricing" cauliflower.
