Preheat oven to 225°F.

Using an electric mixer, whip the egg whites with the salt till stiff peaks begin to form.

Then add in the sugar, a tablespoon at a time, whipping in-between tablespoons, till peaks are still.

Fold in (don't whisk/beat in) almond meal and blackberry jam.

Spoon into a sandwich bag and snip a corner off and pipe circles onto a parchment lined baking tray.

Bake for 1 hour.

Turn oven off and leave baking tray in the oven for another hour.

Let cool afterwards and enjoy either with whipped coconut cream and blackberries or plain.
