My friends are coming over to have a party for my new house. They like eggnog milkshake a lot. So I have decided that I will make the Eggnog milkshake for them. I have never made it earlier. I want to know how much eggs I will need for making eggnog milkshake recipe for four persons? I am going to combine the eggnog, vanilla essence and vanilla ice cream all together for making the milkshake. Do you think this is the right way for making eggnog milkshake?
