Begin with making the squid ink tapioca crackers. Place 2 litres (8 cups) water in a large saucepan over high heat and bring to a boil. Stirring continuously, gradually add the tapioca pearls. Return to a simmer. Cook, stirring occasionally, for 20 minutes or until all pearls are translucent (add a little more water if mixture becomes too starchy and thick). Drain. Rinse
