I Have Heard Of People Going To A Shop,

and mixing their own beans to make coffee to their taste, 

the same for tea, many years ago there was a shop in Piccadilly where you could blend your own tobacco, or indeed snuff, but what blend does this shop offer?

this summer, a unique store opened in Tokyo, located just a few steps away from Tokyo Sky Tree is “Guruguru Shakashaka,”

any idea yet?

this should give you a clue, it is a salt specialty store that lets you explore 600 varieties of salt and then blend your own, you can browse the store on your own but the real deliciousness occurs at the counter where, for 2970 yen, at today's rate £15.98 or $21.10, staff will guide you through 5 different varieties of salt defined by sweet, umami, sour, salty and umami. The taste testing is accompanied by beautiful, blue kanten (agar jelly), which helps accentuate the flavours, and black bean tea, which helps cleanse the palate. Finally, visitors will blend their own salt based on preferences from the taste test and take home 100g of salt, “The fixtures also have a color scheme inspired by salt, where the blue parts are made from dyed linden plywood,” explains Torafu Architects, who designed the interior, “Guruguru Shakashaka” is located on the 4th floor of the Tokyo Solamachi shopping mall, mix your own salt who would have thought it! speaking of salt I was reminded of this,

you could not make it up!
