We are serving 400 women at a tea and in the kitchen will be 35 men plating food (blessed volunteers!!!). The problem is, one of the foods will need a little dollop of whipped cream piped on it before it is served. That's about 800 of these little desserts and 35 men inexperienced in the kitchen. My only thought was filling large pastry bags with the cream and clamping the top closed so it can ooze out or be spilled. Any other ideas???
