Every great four-star chef will have her “secret sauces” as premium materials are used. Usually these are recipes that become signature dishes and ultimately create and define that master chef’s thumbprint for as long as they are in the kitchen.

These are Barnett’s gift to you for being a supporter of the work that he does at Serious Play.
