Can i mix ovaltine and water together? would it be delicious
You can still mix Ovaltine and water together. However, the taste gotten from it will not be good as compared to that of mixing it with milk. It is a personal decision and whether you can afford milk all the time.
It would not be delicious
Delicious? No. Drinkable, yes. Much better with milk.
Yes, but no. It will taste like flavored water.
