Demi glace is the perfect example for how this sytem makes sense! If the central kitchen didn't exsist it would still be made to the same recipie in each individual outlet. Why because the recipie is tried and tested! Demi glace takes a lot of space and time to make, it requires large boilers and a lot of oven space. So why have 5 chefs in 5 kitchens making the same item, move the boilers and ovens to one location, create space in the kitchens, lose 4 chefs and give the chefs in the outlet time to concentrate on other aspects of the MEP. Makes perfect sense to me, in fact it's a bloody good idea. Anyway he's been buying his bread and chocolates in from a third party supplier for years and that hasn't stopped him from getting 3 stars....
