It’s as American as Uncle Sam, apple pie and soda pop but – by ‘eck – it’s now made in Dewsbury.

An artisan peanut butter factory is churning out thousands of jars every week at the Bretton Street Enterprise Centre in Savile Town.

Proper Nutty Peanut Butter debuted at the BBC Good Food Show in Birmingham in November and sold out. And it’s popularity is now spreading.

The brains behind Proper Nutty Ltd are Stuart and Kathryn Franklin who already have their brand in 60 outlets nationwide.

And now the Yorkshire peanut butter is about to conquer the continent with a tasty export deal with Belgium.

Stuart and Kathryn developed their love of peanut butter, not in the States, but while living in New Zealand.

When they moved back to Yorkshire, peanut butter was one of the foodstuffs they missed – so they decided to make and perfect their own.

“There was a lot of trial and error at the beginning to get a product we were happy with,” said Stuart.

“We feel that we have produced a slowly batch-roasted peanut butter with a unique texture that we like to call ‘smunchy’ – a little bit smooth, a little bit crunchy.”

The couple remain hands on despite the growth in their business and Stuart added: “We still make every batch of peanut butter ourselves from loading the peanuts into the roaster to filling the jars with the finished product, although at a capacity of 1,000 jars per day it’s a bit harder work than when we started in our kitchen!”

Nothing artificial goes into the mix. In fact, as it says on the jar, it’s “nowt but nuts.”

Glass jars are used because they can be recycled and because they protect the flavour.

Peanut butter isn’t just for toast.
