Calderdale Bad Boy has been launched onto the unsuspecting taste-buds of market punters and left many gasping for breath. So if you think you're tough enough make your way down to the Calderdale Farmers' Cooperative stall to try it out - it's one mean cheese.

The cheese has been made with the recently launched Naga Naga pickle created by Abdul Rouf and Abdul Mosaad, owners of the Vedas restaurant in Todmorden. And it's the pickle that gives the cheese that unmistakable kick. It even passed the Hugh Fearnley Whittingstall test, when the celebrity chef visited Todmorden in September for the Incredible Edible Todmorden Harvest Festival. And now the cheese is blowing the socks off visitors to markets in Todmorden, Hebden Bridge and Halifax.

Robyn Heap, of Crow Hill End Farm, Hubberton, Sowerby, makes the cheese, which has been heralded as a good hangover cure.

"It's not called Calderdale Bad Boy for nothing but since we introduced it this spicy cheese has proved to be one of our biggest sellers and Parfitts, a wholesale suppliers in Halifax, have said they sell lots too. We sell the Naga Naga pickle as well," said Robyn.

With only 11 cows the farm at Sowerby, which has been in the Heap family for almost 100 years, is the smallest commercial diary farm in the country. Other Calderdale cheeses include Calderdale Royal Blue named in honour of a visit to the dairy made by Princess Anne.

Robyn runs the stalls under the banner of Calderdale Farmers' Co-operative, a group set up to bring the produce of local farmers direct to the consumers of Calderdale.

"We are getting more and more products onto the stalls from nine farms at the moment but we would welcome more. Our idea is to fill these stalls and encourage people to buy all their produce from the markets. We don't see this as competition for the market stall holders here already but a way to bring people into the markets, which will be beneficial to us all. It's so sad when you see so many empty stalls and we want to change that.

"We have more and more people interested, including local beef farmers and one man who sells eggs to fund his battery hen rescue work. We would like to hear from any local crafts people or even local businesses, who would like to showcase their work.

"We have to ask ourselves how long we can continue to import food from all over the world. How can other countries feed their own people if they use all their land to feed us? We have to start thinking local. That is what these stalls are all about," added Robyn, who would like to put local producers in touch with restaurants and cafes in the Calderdale area and would welcome any inquiries.

The Heap family may be the only cheesemakers in Calderdale at the moment but not for long.
