Ever get frustrated with fresh-out-of the-fridge butter that is too hard to spread?

A UK-based company has launched a portable, temperature-controlled butter dish, ButterWizard, which keeps butter at what it says is the optimal spreadable temperature of 65 degrees Fahrenheit.

It has a built-in fan and a chip which together control the temperature, adjustable for different textures, be it super-soft bread, crusty toast or delicate biscuits.

"We were trying to find out what people's frustration with butter was. It's either too hard or too soft," said David Alfille, managing director of East Sussex-based company Alfille Innovations Limited.

"ButterWizard heats or cools the butter and you can adjust the temperature to suit yourself."

Nutritionist Fiona Hunter said: "There are over 16 million UK households buying butter on a regular basis, but one complaint I hear time after time is the lack of spreadability of real butter."

"Butter has been part of diet for thousands of years. The important thing is to spread butter thinly," she added.
