Dear Etiquetteer: I have bought two fruitcakes for a residential building party and am horrified to discover that both may contain partially hydrogenated soybean oil. The third fruitcake source charges $57 for express delivery on top of $100 for two cakes, so that is not an option. My question is do I bring these cakes to the party? If I do, should I tell people that they may contain trans fat? Should I bring an alternative dessert which is trans fat free. I am sure that others will be bringing desserts as well.
The type of party you describe sounds an awful lot like a neighborhood potluck. The whole point of a potluck is that the assembly "takes pot luck:" whatever is brought is there to be enjoyed, whether plain or fancy, kosher, vegan, halal, paleo, macrobiotic, artificially sweetened, lactose intolerant, pre-processed, or partially hydrogenated. So Etiquetteer thinks it Perfectly Proper to bring those Possibly Trans Fat Enhanced Fruitcakes.
A year ago one of Etiquetteer's suggested New Year's Resolutions was "Resolve not to be so insistent about your diet when you’re away from home." A holiday party is the perfect time not to be insistent. Etiquetteer also covered the topic of Diet vs. Hospitality, which could apply here.
Etiquetteer wishes you and your fellow partygoers a Perfectly Proper Time.
