Can't take all the credit for this one. My consultant gave me the recipe and I have tweaked it to fit our family.
80g raw sugar
35g arrowroot
500ml rice milk
approx 1/2 teaspoon cocoa (we have a GF, dairy free cocoa and it is really strong - you might like to adjust this to your taste)
1/4 teaspoon vanilla
Process sugar until of icing sugar consistancy.
Add all remaining, 10mins, 100 degrees, speed 4.
We eat this cold and it certainly thickens once in the fridge and needs a good stir before serving.
For all whose diets require - ENJOY
