Q. Dear Rabino. How can someone warm milk on Shabbat morning for the elderly in our retirement home that is very needed for them for breakfast? It can’t be left overnight even on a covered stove.

A. On Teshuvos Minchas Aviv (p.49) we wrote that one may use powdered milk, that has been already cooked when dried into powder and then they may use the hot water kept on for the coffee use, to dilute it into warm milk.

The above would be similar to making coffee or adding sugar thay is permitted when following the necessary Halacha requirements.
