This is one of those retro recipes that make you wonder why the cheese puff ever went out of style. The puffs can be served warm or at room temperature, but not cold, plan to pull them out of the oven just before your guests arrive. Or have a couple of pans ready to go and put them in the oven during the party. Set the timer and have a cocktail.
A warning: if your kitchen is full of guests when the olives come out of the oven, they will never make it to a serving platter.
*I like to use the unstuffed martini olives from the deli’s olive bar. You can also use jarred martini olives, Santa Barbara Olive Company makes good ones, but are much pricier than the deli option.
