For your squid ink tuille/net, combine the oil, water, flour and squid ink, and thoroughly mix together. Store in a squeezy bottle or sealed container.
Place a non-stick pan over a medium-to-high heat and add a touch of oil till just smoking. Pour enough mixture to make 3-4cm diameter circles, and let cook till bubbling.
Dry - once small holes form, remove with a fine metal spatula or cake lifter. Remove from heat and place on paper towels to absorb any excess oil.
Let it cool completely and keep in a cool dry place in a sealed container.
For prolonged storage, take the small silica capsule out of any new shoe box and keep it in the sealed container to the side of the tuilles. This will remove moisture and allow storage for up to a week.
