Sieve flour, salt and baking powder together in a bowl.
Add rolled oats, raisins and walnuts. Mix well.
Add egg, orange zest, honey, orange juice, melted butter and fresh ginger into another bowl.
Whisk the mixture to mix.
Add grated carrot and mix.
Add the flour mixture. Using a spatula, fold the flour into the liquid. Don't over mix.
Chill the batter for 30 minutes in the fridge. Initially the batter will be liquidy. But on resting it will become thicker.
Preheat the oven to 180°C.
Take about 2 tablespoonful of the cookie batter, roll it into a ball.
If you can't roll it easily then add 1-2 tbsp of flour.
Place the ball on a parchment lined baking tray. Flatten it slightly.
Repeat with the remaining batter.
Bake the cookies for 15-18 minutes or till they become light golden in colour.
For slightly more crispier cookies bake for 20 minutes.
Remove the cookies from the oven and place them on a wire rack to cool.
Store in an airtight container.
