Nick goes to Anglesey to earn his salary (sic) by seeing Halon Môn salt created and how Green & Black’s chocolate is making new use of it.
‘Every day whatever the weather I come down to the water’s edge and use this device,’ says David Lea-Wilson co-founder of the Anglesey Salt Company waving a curious kind of measuring instrument that looks rather like the thing doctors poke in people’s ears.
It is in fact a refractometer and accurately measures how much light bends, or refracts, when it enters water. The more salt dissolved in the water, the more resistance the light will meet and the more it will bend.
This device is crucially important because the seawater here is what goes to make Halen Môn salt, widely regarded as one of the best sea salts in the UK if not the world. And it’s the salt Green & Black’s have chosen to go into their new Dark Sea Salt THIN bar.
