Hafrashas Challah & Tevilas Keilim

A MUCH-NEEDED RESOURCE for the proper fulfillment of these all-important halachos. Some common questions covered:
•How much flour must be in the dough for the chiyuv challah?
•Must I separate challah from my “Yerushalmi kugel?”
•How do I separate challah from a batter?
•Can I send mishloach manos in a dish that has not had tevilah?
•May I send a child to be tovel a dish for me?
These and many more practical scenarios clearly and authoritatively explained. By Rabbi M. Posen
