In a saucepan let melt the butter with water and honey.When it's melted add baking soda and stir quickly for about 10 seconds. Add the butter mixture to dry ingredients and for a dough (it's a little bit crumbly).Form balls the size of a big walnut and put them on a lined baking tray.
Bake at 170°C/340°F for about 10 minutes, they must be crisp on edges and soft inside.
Let them cool completely before storing.
They can be stored for a very long time but don't stack them or, if you do, put a piece of foil or wax paper between cookies or they could stick together.
