hi it is very difficult in my country to find butter milk.......any substitute suggetions pls.......

Place 1 Tablespoon of white vinegar OR lemon juice in a 1 cup measuring cup. Fill the measuring cup with milk.

Let stand 5 minutes.

There's your substitute. I do this ALOT as I never use an entire container of buttermilk.

Or you can make your own buttermilk from heavy cream. When you use heavy cream to make butter you get buttermilk.
