Can you make a egg custard pie 3 days before you need it but put it in fridge?

Yes, you can make an egg custard pie three days in advance and store it in the refrigerator. Ensure it's covered tightly to prevent it from absorbing odors or drying out. When ready to serve, you can enjoy it cold or warm it gently, but be cautious not to overheat, as this can affect the texture.
