knead
Mix or work a dough until it stays together and is smooth and elastic. To knead, dust flour where you are working and on your hands. Add more if needed, while you work. Make a ball out of the
dough and press down once on it with the heels of your hands. Turn the dough about a quarter of the way around and fold it in half towards you. Press again with the heels of your hands. Keep turning, folding and pressing (about 10 minutes) until the dough does not stick.

kosher
Prepared in accordance with Jewish dietary laws.

kosher salt
Pure, refined salt used for pickling because it does not contain magnesium carbonate and thus does not cloud brine solutions. Also used to prepare kosher items. Also known as coarse salt or pickling salt.
