Preheat your oven to 180C/Gas 4
Mix everything together really well – make sure you fully mix in the bicarb and salt – you don’t want to bite into a clump of it!
Scoop it up by heaped teaspoons or scant tablespoonfuls and arrange with 3cm between each cookie on a lightly oiled baking tray.
Gently press each cookie flat (about 1cm or slightly less) thick – tidy up the edges a little, if needed. Finish with an added sprinkling of nuts, seeds or coconut on top, if you like.
Bake in the centre of the oven for about 12 minutes, or until nicely coloured. They’ll be a little soft when fresh from the oven but will firm up on cooling.
