UK supermarket chain Waitrose has rolled out an Android App that encourages users to cook delicious food stuffs by allowing them to download recipes from celebrity chefs Heston Blumenthal and Delia Smith.

Waitrose is making use of a special form of barcode, called Quick Response (QR) code, in a television advert. The code will appear at the end of the advert featuring Smith and Blumenthal.

People can now download popular recipes from Heston Blumenthal and Delia Smith by capturing a photograph of their TV screen with their handset. However, the handset requires a free QR Reader to download a new Christmas app.

The new Christmas app, which is available for Android devices and the iPhone, iPod Touch and iPad, brings a Christmas day planner, a store locator, an advent calendar and `Turkey Timer' that calculates how long one need to cook a recipe.

Quick Response codes, which are used extensively in Asia and America, could not become popular in the UK so far.

Denso-Wave, a division of Toyota, had created the Quick Response codes in the year of 1994.
