Carefully washed and checked to meet strict kosher standards.
Used for dipping in saltwater at the beginning of the Seder.
Shiur (Measurement)
The minimum shiur for karpas is less than a kezayis
(less than approximately 1 oz / 28g).
Many opinions hold that even a small sprig is sufficient.
Since karpas is not a volume-based mitzvah like maror, there is no strict required measurement. Most people use a small sprig — well below a kezayis.
