Delightful White Chocolate Fortune Cookies

1. Preheat the Oven:
   Set your oven to 180°C (160°C fan) or gas mark 4. Line a large baking sheet with a silicone baking mat to prevent sticking.

2. Prepare Your Fortunes:
   Write your fortunes on small pieces of white paper, each measuring 6cm long and 1cm wide. Set them aside.

3. Whisk the Batter:
   In a mixing bowl, use an electric whisk to combine:

   • 2 egg whites
   • 1 tsp vanilla extract
   • 3 tbsp grapeseed oil
   • ½ tbsp cold water
     Whisk until the mixture becomes frothy, about 30 seconds.

4. Combine Dry Ingredients:
   In another bowl, mix together:

   • 100g plain flour
   • 2 tsp cornflour
   • 100g golden caster sugar
     Add a good pinch of salt, then sift this mixture into the egg white mixture. Whisk until you achieve a smooth batter.

5. Chill the Batter:
   Cover the bowl with cling film and chill the batter in the fridge for at least 1 hour. This helps the cookies hold their shape.

6. Shape the Cookies:
   On the prepared baking sheet, place ½ tbsp of the batter. Using a small palette knife, spread the mixture into a thin circle, about 8cm in diameter. Repeat to make a second cookie, ensuring there's enough space between them since they'll spread.

7. Bake the Cookies:
   Bake two cookies at a time for 8 minutes, or until the edges turn golden. Be ready to shape them while they're hot.

8. Form the Fortune Cookies:

   • Use a palette knife to carefully lift each cookie from the baking sheet and flip it over onto a cutting board.
   • Place a fortune in the center of the cookie, then fold it in half, pinching the edges to seal.
   • To shape, gently lift the folded cookie onto the rim of a mug or pan and pull the two corners down. Hold for about 10 seconds to set the shape.

9. Cool the Cookies:
   Transfer the shaped cookies into a muffin tin to help them hold their shape while they cool.

10. Decorate with Chocolate:

    • Melt 150g of chopped white chocolate in the microwave or over a pan of simmering water.
    • Prepare small bowls with sprinkles for decoration.
    • Dip the ends of each cooled cookie into the melted chocolate, allowing excess to drip off, then dip into the sprinkles.

11. Let Them Set:
    Place the decorated cookies on a board to dry. Store any leftovers in an airtight container for up to three days.
