Preheat the oven to 200C/400F and line a baking tin with greaseproof paper.
Place the cornmeal, buttermilk, sugar and melted butter into a large heatproof bowl and stir until combined and smooth.
Place over a double boiler on medium heat for 10 minutes, stirring to ensure it remains smooth as it cooks.
Remove from the heat and scrap down the sides of the bowl to ensure the cornmeal mixture doesn’t stick.
Allow to cool for 5 minutes.
Meanwhile, stir the baking soda and cold water together until the baking soda has dissolved.
Peel the apples and grate onto a plate or into a bowl, discarding the cores.
Place baking soda water mixture, eggs and apples into the cooled cornmeal mixture and stir together until smooth.
Pour into the prepared baking tin and smooth out on top.
Place in the oven and bake for 30 minutes until lightly golden and a skewer comes clean.
Allow to cool to warm and slice into even squares.
Serve with a little honey (wild honey, if possible) and enjoy.
