Refer to the below for a background on "outkitchen".
For food vendors who insist on absolute quality, or those vendors currently operating without a food permit, hiring a commercial grade kitchen to produce stock
poses as a very viable option.
In every food market you will find on average 80% of food stalls are actually existing without a legitimate food license as they produce their goods in their own home. This is in fact illegal, due to the safety and cleanliness issues.
For a very modest fee, these vendors would be able to use all the equipment they need, at any time of the day, for any period of time. This would give the vendors a superior cost saving as they do not have any set up costs, nor do they have the ongoing maintenance issues.
