How Much Challa May Be Missing

Less than 1/48th missing is still considered a whole loaf. So if you only have two challot (or other loaves of bread) for a Jewish festival, you might be able to use one loaf twice:
  • Wash your hands,
  • Say ha'motzi,
  • Cut off a piece that is less than 1/48th of the loaf, and
  • Eat it.
Reason You may consider the remainder of that loaf as still being a full loaf and you may re-use it for your Jewish festival morning meal.
Note If you have pieces of bread or other mezonot, you may:
  • Cut off less than 1/48th of the loaf,
  • Eat the additional pieces of bread to make a total of at least 1.9 fl. oz., and then
  • Re-use the same loaf for Jewish festival morning.
