I am hosting a holiday open house for approx. 40 people next weekend. I am primarily going to offer appetizers and desserts but wanted to also offer something a bit more substantial to my guests. Based on great suggestions I received on these boards, I'm thinking of putting out a spiral sliced ham. I have never cooked or served ham before so I'm not sure what to do. I wanted to het a precooked honeybaked ham but they are pretty expensive so I thought I could make a better one myself for less money. So, I am going to buy a sprial sliced ham from my local market. How big should it be? Should I buy bone-in or boneless? What is the best cooking technique? Good glazes? What is the best way to serve and avoid having a big mess at the buffet table? So many questions, thanks in advance for your help!
