When I was younger I liked hosting fancy dinner parties. In college they were usually accompanied with a "How to Host a Murder" game. I tried to match the meal to the setting of the game. I often tried new recipes on my unsuspecting guests. There were times that nobody ate one or more of the items.
My biggest disappointment occurred with family. One Christmas I made a four course meal for family and some friends. There were quite a few who flat out refused to eat some of the dishes. The biggest objection was to the vichyssoise, a cold potato soup similar to gazpacho. Plus, they wanted to have all of the courses at once. I haven't tried serving an elegant meal to my family since that episode.
I tried a lot of foods during my dating years. I always wanted to be "cool." I'm not a fan of peaches. I went on a weekend excursion with a guy a really liked. He stopped in a little town in Wyoming. When I got back from the little girls room he presented me with a peach. He declared that he had spent time picking the very best peach for me. So I ate it. I praised him for picking this delectable treasure for me. I vowed, to myself, that if we got married I'd have to tell him I didn't like peaches. It bit me again later that trip when he showed up with a peach shake from the local market. He said he knew he had to get me one because I loved peaches so much. Darn my acting ability!
Now I try to keep an open mind. There are foods I still don't eat on my own. But, if you invite me to dinner I will try most of what is placed in front of me.
