The Mast Brothers of Mast Brothers Chocolate. They started in their apartment, wrapping chocolate in beautiful paper they sourced from the markets and paper shops. Their business grew rapidly and they now import tons of beans from around the world, to make 'bean-to-block' chocolate. There was some controversy with claims that they simply bought processed chocolate from the likes of Valrhona and just melted it down at the start. But it appears at least they're not doing that now.
