I am having a cocktail party and will be featuring a whipped potato bar. I know that it is considered proper etiquette to eat mashed potatoes with a fork, but in this case (serving the potatoes in a martini glass) would you go with a dinner fork, salad fork, or teaspoon?
In this case, the martini glass serves as a de facto bowl, thus I say you should use a spoon. Whether Emily Post would agree with me, I’m not sure. My basic thought on the subject is: if you’re eating it out of a bowl, you probably want a spoon; whereas if you’re eating it from a plate, you probably want a fork. While there are exceptions to the rule, it answers the conundrum correctly 19 times out of 20.
