You can buy smoothie mixes very cheaply – find them in the frozen food section of your supermarket. Buy some, plus apple juice and you are good to go. Alternatively try this. Makes for two:
- An old banana
- Glass of orange juice
- 50-80ml plain yoghurt depending how thick you like it
- Glass of frozen fruit, e.g strawberries, or half a glass of fresh chopped fruit which will squish down more than frozen
Put all of it in a blender and whizz until smooth. Yes you can blend from frozen. Adjust the quantities until you get the consistency you prefer.
