Our final low-GI delicious recipe for the week is dessert: Oaty Plum Crumbles...

GI Tip: Plums, like cherries, apples and pears, are a particularly low-GI fruit. The crumble topping is made with jumbo oats, which helps to keep the GI of the overall dessert low, too. Serves 4

750g ripe plums, stoned and sliced

4tbsp water

1-2tbsp light muscovado sugar

Half-fat creme fraiche, low-fat custard or ice cream, to serve

For the crumble topping:

100g wholemeal self-raising flour

3tbsp polyunsaturated margarine

70g dark muscovado sugar

80g jumbo oats

1/4tsp freshly grated nutmeg

Caster sugar, for sprinkling

Place the plums, water and sugar in a saucepan. Heat until simmering, then simmer for 10-15 minutes, until the plums are just cooked and soft.

Meanwhile, to make the crumble topping, put the flour in a mixing bowl, add the margarine and rub it in with the tips of your fingers. The mixture should resemble breadcrumbs. Add the sugar, oats and nutmeg, and mix.

Divide the plums and their cooking liquid between four ramekins. Top with the crumble mixture, then sprinkle with a little caster sugar.

Bake in a preheated oven at 180C/Gas Mark 4 for 15-20 minutes, until the topping is golden and the fruit is bubbling. Serve warm with some half-fat creme fraiche, low-fat custard or ice cream.
