mordecai98,
Mazel Tov ! I’m jealous. It’s a few years for me. My coins are shined up with no place to go.
Talk about Pidyon Haben in general, and maybe some haaros about it. It’s such an infrequent mitsvah and people are usually busy thinking about the food. Talk about how eating at a P”H is mechaper because it is called Pidyom in the Torah one time. Pidyom is short for Peh Daled (gematria of 84) Yom -> that is that eating at a pidyon haben is like fasting 84 days, which can atone for the worst of sins. That’s why there is a custom to serve food that people will take home and use further, like garlic or sugar, which can be put in soup or other foods.
