Do the Isrealites still kill lambs and put the blood on the doors?

Putting blood on the lintel of the door was a one-time commandment that pertained only to the generation which was brought out of Egypt during the redemption of the Children of Israel from bondage in Egypt. Subsequently, Jews are commanded to sacrifice a lamb at the Temple in Jerusalem on the afternoon before Passover, and to roast the meat of it to eat at the seder. Now that the Temple has been destroyed and not yet rebuilt, the commandment to offer the lamb as a sacrifice cannot be observed. One of the symbolic foods at the seder is a roasted shank bone to remind us of the paschal offering. Lamb itself is NOT eaten bye Ashkenazi Jews at the seder now that the Temple has been destroyed and not yet rebuilt, lest we mistake that lamb for the commanded lamb sacrifice.
