Step 1 : Introduction to the question "The annual food fight festival in Buñol, Spain, features what fruit?"
...Ripe tomatoes are the weapon of choice at the annual La Tomatina festival in Buñol, Spain. This rowdy food fight festival comes around on the last Wednesday of August each year. Projectile tomatoes rule Buñol on this day, beginning in 1945. It isn't an "anything goes" food fight, however; there are rules. For example, you must squash your tomatoes before throwing them to avoid injury to your fellow revelers. And tomatoes are the only fruit allowed. Source: MSN.com
