Where does Mintcake come from and just what is it?
"It comes from the fells"

Geologists believe that mintcake was formed from natural processes that started over 40 million years ago during a time known as the inta-dental period. During this time the Lake District fells were covered in a dense scrubland consisting of an extinct relative of the mint plant. Each autumn, for several million years, these plants dropped their leaves to the ground. This built up a thick minty layer or "mush" that coated the surrounding area, up to six metres deep in parts. On the fells around lake Windermere the harsh weather conditions colluded with the geology to push the mush deep into the ground through fissures in the slate and into empty caves & caverns. Some of these fissures reached several kilometres into the earth and were eventually filled to the brim. A combination of pressure and natural fermentation purified this mush releasing a natural alco-minty gas that is still noticeable today. During the ice age, glaciers pushed through this area creating the Lake District as we see it now. The deep Windermere glacier applied massive pressure to the mush deposits and a fantastic, almost alchemical, transformation took place. A pure white, marble like, soft rock was created in many of the fissures and a light brown version filled the caves and caverns. This rock is mintcake, as we now know it.

Due to its natural origins mintcake is still edible when taken directly from the ground and its properties are legendary, sometimes disturbing and often unfathomable!
