Mystery Recipe Challenge
Each person secretly picks a recipe in a cuisine the other person isn't familiar with. Shop for ingredients separately, keeping your dish a surprise until you're both in the kitchen.
Cook your dishes simultaneously in the same kitchen, helping each other only when specifically asked. Set a timer and see who finishes first, documenting all the chaos and mistakes along the way.
Present your dishes with elaborate plating and fake restaurant names. Taste and score each other's creations on taste, presentation, and creativity, with the loser doing dishes.
