Preheat the oven to 180ºC / 350ºF / Gas Mark 4. Line 10 holes of a muffin tin with muffin paper
Mix the flours, bran, baking powder, bicarbonate of soda and salt together in a bowl and stir in
the sugar. Whisk the honey, egg and buttermilk together in a jug.
Pour the wet ingredients into the dry and stir briefly to combine. Don't over mix - the mixture
should still be a little lumpy. Fold in the blueberries.
Spoon the mixture into the paper cases and bake in the preheated oven for 20 minutes until risen
and lightly browned.
Remove the muffins from the oven and leave to cool in the tin. Serve warm or cold.
