Preheat the oven to 350f. Line a baking tray with baking parchment or a silicone mat. In a large bowl, add all but 1 tbsp of the flour, the sugar, baking powder, baking soda, raisins and salt.
Break the eggs into a separate bowl and whisk gently for a few seconds. Pour all but 1 tbsp of the egg into a separate small bowl. Add in the buttermilk and melted butter to the large bowl.
Pour the egg mixture into your dry flour mixture and stir – initially using a wooden spoon, and then your hands – until you get a sticky dough. Don’t overmix or you’ll end up with tough bread.
