Heat the oven to 200°C/gas mark 6.
Melt the butter in a small pan, then leave it to cool slightly.
Tip the oatmeal, flour, baking powder, Parmesan, and sesame seeds into a bowl.
Add half a teaspoon of salt, then pour in the melted butter.
Add 5 tablespoons of boiling water, then bring the mixture together in a firm dough, adding another 1-2 tablespoons of boiling water, if needed.
Turn the dough out onto a lightly dusted work surface, then roll out to the thickness of a one pound coin.
Cut into small squares or 3-4cm triangles, then transfer to a baking tray lined with baking parchment.
Re-roll any offcuts, then repeat.
Bake for 12-15 minutes, until golden.
Leave to cool on the tray for a few minutes, then transfer to a wire rack to cool completely.
Serve the oatcakes with soft cheese and grapes.
