If you're going to the Kentucky Derby and plan on indulging with a few mint juleps, be sure to bring some extra cash. This year, the price of a mint julep is $22. That's roughly 30 times more than the 75 cents patrons paid for mint juleps in 1940, per USA Today.

The executive chef at Churchill Downs explains how he and his team make juleps for the 400,000 people who come through their gates.

1. Take a tall glass, mix some sugar with a little water at the bottom (if you want to get REAL fancy, here's a good recipe for a simple syrup). 2. Muddle some mint at the bottom of your glass. 3. Throw in some ice. 4. Pour in your favorite bourbon.
