Chocolate custard (sugar free)

I made up a batch of sugar-free custard last night to have with a sliced pear. Custard powder is sugar free so I just added sweetener instead of sugar. It was a real homely treat. Oddly this is the first time I've made custard since being diagnosed two years ago.

The recipe couldn't be simpler: 1 tablespoon of Birds custard powder, 1 tablespoon of sweetener (or equivalent), 1 teaspoon of unsweetened cocoa powder (I used Green & Black's Fair Trade) and 1/2 pint of milk. Mix dry ingredients with a little milk to make into a paste, heat up the milk (microwave) and slowly add the hot milk to the paste while heating in a saucepan.

The only sugar present is from the milk (5% sugar) and naturally in the pear (~10% sugar) so it's around 8% sugar in total which is pretty nicely acceptable for a diabetic.
