This is a recipe from my mother's old recipe book. It's ideal for ice cream.
½ Teaspoon Vanilla Essence
2 Tablespoons water
1 Tablespoon Golden Syrup (May substitute 1oz sugar)
Mix all ingredients and heat gently until the cocoa has fully dissolved. Do not boil as this will spoil the shiny appearence.
I've served this in a chocolate fondue dish using a tea light to keep it warm.
