Dough:
two cups of flour
two eggs
one cup of water
a pinch of salt
Filling:
meat
onion
salt
pepper
For veggies:
pumpkin
onion
salt
pepper
sugar
Or whatever mixture you want
Make the dough soft. Flatten it thin and cut into large circles (8cm in diameter). Chop the meat and onion, place them in a bowl and add salt and pepper. Put a handful of the blend on a circle of dough, fold it in two and close the open half-circle with a pinch. Repeat with the rest of the kreplach.
Cook in a steaming pot for 45 minutes after the steaming water begin to boil.
To make it veggie, chop the pumpkin and onion and add a bit of salt, black pepper and a little sugar. If you want to combine both kinds and help your guests make out the difference, you can close the kreplach to make different shapes.
