The question is whether pepper qualifies as a valid food for eruv techumin and whether the local custom of using half a Lot meets the required Talmudic measure. The Chasam Sofer validates the ancestral practice retroactively but rules that going forward communities should use approximately 2 Lot and 3 Quentel per person.
