A combination of fruits and/or vegetables always makes a great recipe. A milkshake that proved delicious was one that the class of my special child made and liked so much at Resources for the Blind and it was a mixture of bananas, mangoes and apples. I experimented on that combination with a revision of the proportion of fruits and added a fruit that really made it the most delicious milkshake I've ever tasted, and that is kiwi.
Here's the proportion that I used:
2 bananas
1 mango
1 big apple
1 big kiwi
1/4 cup sugar
Around 150 ml. of milk (I used small tetrapacks so I can switch to low fat milk for me and my husband)
Procedure:
Peel, slice and blend the above ingredients in a blender until smooth (that will take less than a half minute), transfer in a bowl then set aside. Crush the ice small enough to be blended till fine or if you're using an ice crusher or something like a Matstone juicer that has an ice shaver like the one I used, you can use tube ice.
Pour a glass of shaved ice on the blender and add one cup of the blended fruit mixture in the blender and blend for 10 seconds. More milk may be added for the children before blending. That can be good for 2 persons. I think I was able to produce 6 glasses all in all.
