Full Story

A true Master must know his field by heart.

He must know the tools of the trade and the theory behind them.

He must know all or its sub-field and components: their names and their use; how they respond and interact; all their tiny intricacies, strengths and weaknesses.

Moreover, he has to understand them, and has to have the creativity and insight to apply his knowledge to find novel ways; to find new functions and explore new applications.

If and only if he has proven to possess these skills, and continues to prove them in the heat of the battlefield, may he truly be called… Chef

The road to becoming a true Chef is filled with hardships and challenges. Aspiring Chefs must train hard and push themselves to the limit. And we are here, to test them. Hack in the Box proudly presents, the Culinary Tour de Force!

The Culinary Tour de Force – or CTF – is a pressure test of skills and ingenuity, where aspiring Chefs are challenged to prepare a series of exotic dishes within a short time frame. Contestants have 48 hours to analyze the recipes, find all the necessary ingredients and assemble them to complete their dish. Previous years have included such delicacies as

·         Cuckoo with Stack Canary Paté
·         Lattice Salade with C-Shells
·         Pickled Python with a side of Perl oysters

As even just gathering ingredients will prove to be a challenge, contestants will be awarded points both for the collection of individual ingredients and the successful completion of a recipe.

As a true Chef must be able to function as part of larger kitchen staff, the recipes are designed to be a multi-man effort. This means contestants are encouraged to collaborate and form teams of up to three contestants per team.


The top three teams will be awarded with special scholarships to help them on their way to becoming true Chefs.

1st Place – USD3,000

2nd Place – USD2,000

3rd Place – USD1,000

The CTF will be held on-site at Hack in the Box Amsterdam, on May 26th and 27th 2016. To entice both professionals and amateurs alike to join the CTF, a small teaser will be held as a taste of what is to come. This teaser will contain a small recipe that can be completed entirely on-line and has a much lower time limit.

The starting date of the teaser will be announced at a later date.
