Vanilla Bean Marshmallows

From Anne's Food

makes about 80 2 tbsp + 2,5 tsp powdered gelatine 125 ml cold water 125 ml warm water 125 ml white baking syrup (or corn syrup) 500 ml sugar 1/4 tsp salt 2 egg whites 1 vanilla beann 200 ml powdered sugar Prepare a tin - mine was about 24*30 cm - by greasing it with oil and sifting a thick layer of powdered sugar to cover the bottom and sides of the pan. Pour the cold water in the bowl of your mixer, and sprinkle in the gelatine powder. Mix warm water, white baking syrup, sugar and salt in a saucepan. Boil until the syrup is 116°C. Pour it over the gelatine (it's gping to bubble fiercely) and stir until combined. Beat the mixture on high speed until it's really thick, white and shiny. (5-6 minutes.) In a separate bowl, beat the egg whites until stiff. Mix those, and the seeds from the vanilla bean, into the marshmallow batter. Whisk until combined. Pour the batter into the prepared tin. Try to get a fairly even layer - it will be easier if you sift some powdered sugar on top, and press with the back of a wooden spoon. Sift an even layer of powdered sugar on top, and place the tin in the fridge for at least three hours. Next, turn the marshmallow slab out onto a cutting board. Cut into large dice, and sift more powdered sugar so that every side is covered - if not, it will be very messy. When you're done, keep at room temperature, in an air-tight jar.
