substitute mango for papaya

by Bill

I read the protein shake recipe and questioned the "drinking whey". Where do I find it? Also, can I substitute mango for papaya?

Dear Bill,

Drinking Whey is the liquid that remains after milk has been curdled and strained - it is very healthy and low fat. Instead of whey you may have low fat milk too. Of course you could substitute mango for papaya.

All the best,
Gabriela
