1) Matzah may not be eaten on Erev Pesach. [This is the Din; our Minhag is to refrain from 30 days before Pesach]. The general Minhag is to refrain from eating Maror too. Our Minhag is to also refrain from eating the ingredients of the Charoses — until the meal at the 2nd Seder.1

2) In following with this Minhag, many do not serve apple compote until the 2nd Seder night. Nonetheless, one need not refrain from eating nutcake during this period.2

3) I was asked by a pregnant woman that was suffering from heartburn, if she could eat almonds on Erev Pesach. I answered ‘Yes’, since our Minhag is to use walnuts for the Charoses rather than almonds.3

4) There is no need to refrain from eating eggs or the vegetables used for Karpas.

5) I have not heard of any restriction on eating roast meat on Erev Pesach. There are, however, restrictions on how much wine one may drink in the last quarter of the day. Also, during the same period one should limit one’s eating so as not to impair one’s appetite for the evening.4

6) The time for sacrificing the Korban Pesach in the Beis HaMikdash is on the afternoon of Erev Pesach. Due to this, this afternoon has a similar status to Chol HaMoed, and — in the first instance — one should cut hair and trim nails before midday.

7) After the fact, past midday one may have one’s hair cut by a non-Jew, while one may trim one’s nails oneself too.5

8) Where an Eruv has been established in order to permit carrying from one dwelling to another, it is customary to renew the Eruv on Erev Pesach. In order to justify the berachah said when doing so, the original Eruv should be eaten before this renewal.6
