Sarah and I have been over this dilemma several times.
We tried a zillion different recipes, and many strategies for passing the zucchini off to somebody else, or "nipping it in the bud" by picking the flowers.
Here's one we never thought of:
Simply cut them into spears and pass them off onto the hip downtown party set.
My buddy Chris and I crashed an Africa-themed party for Eve Ensler (the Vagina Monologues lady), and were surprised to find that all the intellectuals and people-about-town were mad about zucchini.
We're thinking about using this strategy to get rid of surplus items around the home. Simply host an exotically-themed party, invite the hip, the mod, and the fashionable, and pass off your worthless junk as party favors.
