For all you knitted yoghurt makers out there, I've found a fantastic book with some really scrummy recipes in: The big book of Juices and smoothies is £5 from Lakeland.
I've only had it a week, and already we are total converts. Some of our favourite recipes (all just whizzed quickly in the blender) so far are:
Creamy Pink Banana
1 banana
2 handfuls of strawberries
5 tbsp yoghurt
8 tbsp apple juice
Berry Mango
1 mango
1 handful strawberries
1/4 pineapple
5 tbsp yoghurt
6 tbsp pineapple juice
Creamy Apple Freezie
4 tbsp frozen stewed apple
1 fresh apple, cored, chopped and peeled
4 tbsp yoghurt
1/4 tsp cinnamon
1/2 tsp vanilla essence
few dashes apple juice
The kids enjoy helping to make them too.
