Remember to buy and eat Teide stones when you come to Tenerife!
A product from La Laguna, in the north of Tenerife. The stones are made of almonds from Tenerife that are covered with sugar, coated with Chocolate and dusted in Cocoa Powder. They look like lava stones.
The taste is lovely! I bought a package yesterday at the Philippe mercadona in Las Americas. A nice present to bring with you home as a small gift to friends.
Sometimes they even sell them at the restaurant in the Teide national park.
