Project Kitchens
Originally developed by Seb Paquet, Project Kitchens is a wonderful tool that can help propel early stage ideas into concrete next steps
The format brings together a small number of people who have projects they would like assistance with and puts one project at a time under the spotlight for around 25 minutes. Generally 3-4 projects can be covered in a 2-hour Kitchen. A Chef facilitates; with the role of creating an atmosphere of trust, keeping things rolling, and avoiding wasting time through the process.

We have used this tool in person at Lifehack Oro and the Flourishing Fellowship. We have also experimented with using the tool online, you can read more about that here.
