For enough to feed two little ones as an after dinner treat (or one hungry one) you will need:
200ml milk of your choice (dairy, coconut, almond, rice...)
2 tsps or so of rice malt syrup (or maple syrup or honey of you are not avoiding frustose like me)
1 egg yolk (ours came courtesy of 'Lavender' chook)
3tsp corn flour
and a splash of vanilla extract.
Bring the milk and vanilla to just below boiling point over a medium heat. Meanwhile, in a small jug, stir/whisk egg yolk, syrup and cornflour into a smooth paste. Carefully pour about half of the hot milk into the yolk mix and stir/whisk like crazy for a bit then tip the yolk mix back into the saucepan with the remaining milk and stir/whisk til it thickens. Eat with or without raspberries.
