Preheat the oven to 220 degrees C. Grease a baking tray.
In a bowl, mix together the salt and flour, then cut in the butter and rub between your fingertips until the mixture resembles breadcrumbs. Add the sugar and coconut (if using) then mix well. Mix in the egg and milk until a dough forms then divide the mixture into 12.
Shape each into a bun and place on the prepared tray. Make a well in the centre of the bun using your thumb and spoon a little jam into the hole.
Bake in the preheated oven for 10 to 12 minutes, until they are brown and risen. Remove from the oven and allow to cool before serving and enjoying.
You can try varying the recipe using different flavour jams.
