Thanks for the appreciation, Zelita. And glad you're going to try out my recipe. If you live in India, remember to store it in the fridge and then enjoy it for weeks!
You're most welcome, Lalita. One can of condensed milk measures 1 and 1/4 cup. So you'll have to add 1/4 of the quantity of chocolate more. That is you'll have to add 375g chocolate (instead of 300g).
Wilma, whether you use amul or milkmaid, the condensed milk in one full can weighs almost 400g and in volume is around 300ml. That is 1 and a 1/4 cup. From this, you need to use just 1 cup for my recipe.
