Love, love this recipe. How far ahead can it be made? We are having guests Christmas Eve and I would love to serve, but there is so much going...

The olives stay nice for about 24 hours in my kitchen. But if you wish to make them ahead, I wold advise heating them a bit before serving. The crusty outside will become soft if they are old, and part of the deliciousness is the crunch of the crust. Let me know what happens!
