Preheat oven to 175Â°C/Gas Mark 4.
In a small bowl stir the hot water into 2 tbsp of the honey. Add the sesame seeds and stir well to coat. Set aside.
In a separate bowl, mix together the flour, baking powder and salt.
In another separate bowl, cream together the butter, sugar and remaining 2 tbsp of honey, until light and fluffy. Beat in the flour mixture - the dough will become quite stiff.
Pinch off small pieces of dough and roll into 1 inch balls. Roll into the honeyed sesame seeds to coat and place 1 1/2 inches apart on a lined baking sheet. Flatten each one slightly with the bottom of a glass.
Bake in the centre of the oven for 15 minutes of until just golden.
Leave the cookies to cool for 1 minute, then transfer to a wire rack to cool.
