I suggest level leaderboards for each recipe. Here is a draft of the rules.

Objective:

• Serve the best dish

Rules:

• Use 'Leaderboard Challenge' mode
• Timing is measured using the in-game timer (shown as 'Realization time')
• All available criteria (Flavors Taken, Thermal Treatment, Technical Rating, and Temperature) must be 100%
• Perks are allowed

I will create the leaderboards one week later if there is no feedback. Feel free to post your opinion!
