The Knickerbocker Glory Story

This is a short story. On a sunny day, I sit on a terrace and order a fantastic Knickerbocker Glory sundae. Next to me, at two tables, were six young women. They are lawyers from the same academic year. Cheerful stuff. Just like every year, they want to do their birthday differently next year. This time, Belgian Lisa comes with a concrete proposal. They will hire a private chef for a special dish that she likes. If Lisa reveals a tip of the veil, it will provide great entertainment. A recipe is included.
