Q. What is the Halacha with regards to the hafrashas challah. what should be done after the hafrasha? burn it in the oven double wrapped? on the stove top? double wrapped (less then a k’zais) and then thrown out?

Thanks

A. Horav Shlomo Miller Shlit”a advices to place a small piece of dough (more or less the size of today’s olive — more than that could create a problem of baal-tashchis, or unnecessary destruction of food), into the oven until it is completely burnt. However, since challah is not permitted for consumption today, an appropriate and efficient way to dispose of the challah is to double wrap the piece in aluminium foil, and to place it in a corner of the oven while baking other items, until it is completely burnt.
