5. Exploring definitions

While precisions have received a great deal of attention, they should not obscure the fact that they are cultural artifacts, adding to the main part of recipes, which is the definition. It is therefore essential to explore definitions. It should be noted that the animal and plant tissues that make up the bulk of the human diet are, more often than not, predominantly composed of water, so that their heat treatment takes place at a temperature limited by the boiling point of water, for the inside of the tissue (inner part), while the outside (outer part) can be brought to a temperature of over 100°C when the surface water has evaporated and a crust has formed.

As a result, it becomes legitimate to include culinary definitions at the basis of the study:

• exploring the heat treatment of plant tissue at 100°C in an aqueous...
