I need an idea for a French Cuisine Product for my personal project.?

I am doing a Project on French Cuisine. I had to talk about how it has been influenced by History and Economics, Neighboring Countries and Immigration, and Local Availability. I mentioned something about how corks kept fizz in champagne and how a French Chef discovered second fermentation. I also mentioned the introduction of coffee. Now I have to make a product that is tangible and shows my abilities to recreate what I have learned. Any ideas? Please Help!
