The approach to cooking is entirely practical. The emphasis of the book is on making medieval cookery accessible by enabling today's cooks to produce authentic medieval dishes with as much fidelity as possible. All the ingredients are readily available; where some might prove difficult to find, suitable substitutes are suggested. While modern ingredients which did not exist in the Middle Ages have been excluded (corn starch, for example), modern time and energy saving appliances have not. Authenticity of composition, taste, and appearance are the book's main concern. Unlike any other published book of medieval recipes, Pleyn Delit is based on manuscript readings verified by the authors. When this was not possible, as in the case of the Arabic recipes, the best available scholarly editions were used. The introduction provides a clear explanation of the medieval menu and related matters to bring the latest medieval scholarship to the kitchen of any home. Pleyn Delit is a recipe book dedicated to pure delight - a delight in cooking and good food.
