I seem to recall an Ashkenazi minhag not to eat any form of lamb on seder night. I don't mean the widely spread custom not to eat a roasted lamb, but even , for example, braised lamb shanks.
Is this indeed a widespread minhag among ashkenazim? Which communities practise it?
This article says:
Today, in the absence of the Temple, the mitzvah of the Korban Pesach is memorialized in the form of a symbolic food placed on the Passover Seder Plate, which is usually a roasted shankbone. Ashkenazic Jews have a custom of not eating lamb or goat during the Seder in deference to the absence of the Temple. Many Sephardic Jews, however, have the opposite custom of eating lamb or goat meat during the Seder in memory of the Korban Pesach.
It seems to be a widespread custom among Ahskenazim not eat any lamb in any form. I don't know of any Ashkenazy who does otherwise.
IMO, this is not a chumra, but rather there seems to be some basis to the thinking. It seems to be the same reasoning why I have seen many Hagaddah instructions state not to point to a roasted lamb shank on the Seder plate while saying "Pesach zeh".
