ralisation, and one that is worthy of more serious consideration than it has received.
All our handicraft, however great may be the skill employed, amounts to no more than this. The miner moves the ore and the fuel from their subterranean resting-places, then they are moved into the furnace, and by another moving of combustibles the working of the furnace is started; then the metals are moved to the foundries and forges, then under hammers, or squeezers, or into melting-pots, and thence to moulds. The workman shapes the bars, or plates, or castings by removing a part of their substance, and by more and more movings of material produces the engine, which does its work when fuel and water are moved into its fireplace and boiler.
The statue is within the rough block of marble; the sculptor merely moves away the outer portions, and thereby renders his artistic conception visible to his fellow-men.
The agriculturist merely moves the soil in order that it may receive the seed, which he then moves into it, and when the growth is completed, he moves the result, and thereby makes his harvest.
The same may be said of every other operation. Man alters the position of physical things in such wise that the forces of Nature shall operate upon them, and produce the changes or other results that he requires.
My reasons for this introductory digression will be easily understood, as this view of the doings of man and the doings of Nature displays fundamentally the business of human education, so far as the physical proceedings and physical welfare of mankind are concerned.
It clearly points out two well-marked natural divisions of such education—education or training in the movements to be made, and education in a knowledge of the consequences of such movements—_i.e._ in a knowledge of the forces of Nature which actually do the work when man has suitably arranged the materials.
The education ordinarily given to apprentices in the workshop, or the field, or the studio—or, as relating to my present subject, the kitchen—is the first of these, the second and equally necessary being simply and purely the teaching of physical science as applied to the arts.
I cannot proceed any further without a protest against a very general (so far as this country is concerned) misuse of a now very popular term, a misuse that is rather surprising, seeing that it is accepted by scholars who have devoted the best of their intellectual efforts to the study of words. I refer to the word _technical_ as applied in the designation ‘technical education.’
So long as our workshops are separated from our science schools and colleges, it is most desirable, in order to avoid continual circumlocution, to have terms that shall properly distinguish between the work of the two, and admit of definite and consistent use. The two words are ready at hand, and, although of Greek origin, have become, by analogous usage, plain simple English. I mean the words _technical_ and _technological_.
The Greek noun _techne_ signifies an art, trade, or profession, and our established usage of this root is in accordance with its signification. Therefore, ‘technical education’ is a suitable and proper designation of the training which is given to apprentices, &c., in the strictly technical details of their trades, arts, or professions—_i.e._ in the skilful moving of things. When we require a name for the science or the philosophy of anything, we obtain it by using the Greek root _logos_, and appending it in English form to the Greek name of the general subject, as geology, the science of the earth; anthropology, the science of man; biology, the science of life, &c.
Why not then follow this general usage, and adopt ‘technology’ as the science of trades, arts, or professions, and thereby obtain consistent and convenient terms to designate the two divisions of education—technical education, that given in the workshop, &c., and technological education, that which _should be_ given as supplementary to all such technical education?
In accordance with this, the present work will be a contribution to the technology of cookery, or to the technological education of cooks, whose technical education is quite beyond my reach.
The kitchen is a chemical laboratory in which are conducted a number of chemical processes by which our food is converted from its crude state to a condition more suitable for digestion and nutrition, and made more agreeable to the palate.
W. Mattieu Williams opens The Chemistry of Cookery not with a recipe but with the boiling of water, insisting that even this familiar act is poorly understood by most cooks. His approach is relentlessly experimental: he describes injecting boric acid into a live sheep, then tracking the meat's condition over months, and later eating it with his family. The book is structured as a series of chemical investigations into everyday kitchen processes, from the setting of jellies to the softening of vegetables.
Williams writes with a confident, conversational voice, often addressing the reader directly and drawing on his own observations. He is as likely to cite a German physiologist as he is to describe the contents of his own larder. The result is a work that bridges domestic science and laboratory chemistry, aimed at an audience of householders and cooks who wish to understand the 'why and wherefore' of their craft.
The Boiling Point as a Starting Point
Williams devotes his first chapter to the boiling of water, a subject he considers fundamental yet widely misunderstood. He argues that most cooks boil water too vigorously, wasting fuel and altering the texture of food. His explanation draws on the physics of latent heat and the behavior of bubbles, but he never loses sight of the practical outcome: a properly boiled egg or potato. The chapter sets the pattern for the rest of the book: a chemical principle is introduced, then immediately applied to a common culinary problem.
This focus on the seemingly trivial is deliberate. Williams believes that small corrections in technique can yield significant improvements in both economy and quality. He is particularly attentive to fuel efficiency, a concern that reflects the domestic budgets of his Victorian readers. By starting with water, he establishes his authority as a chemist who can explain the simplest phenomena, and he invites the reader to see cooking as a series of controlled chemical reactions.
Preserving Meat with Boric Acid
One of the most striking passages in the excerpts describes Williams's own experiment with meat preservation. He injected a sheep with boric acid before slaughter, then monitored the carcass over several months. The account is precise and personal: he notes the date of the meal, the condition of the meat after twenty-two days of hot weather, and the eventual 'gamey' flavor that preceded spoilage. He even reports that his family ate the meat without complaint.
This episode reveals Williams's willingness to test his theories on himself. He does not merely cite scientific literature; he generates his own data. The discussion of boric acid extends to milk preservation, where he mentions 'glacialine' and the work of M. de Cyon. Throughout, Williams maintains that small quantities of borax are harmless and even beneficial, a claim that reflects the regulatory assumptions of his era. The passage is a vivid example of how the book blends chemistry, personal testimony, and advocacy for new techniques.
Vegetable Cells and Gelatinous Analogies
When Williams turns to vegetables, he draws a structural parallel with animal tissues. He cites Haller's dictum that half the animal body is gelatin, then argues that plant cell walls play a similarly fundamental role. Using a hyacinth root as an example, he describes how to observe cellular structure with a microscope, noting the transition from rounded cells to oblong ones and the central spiral tubes.
His point is practical: because cell walls constitute more than half the bulk of most vegetables, cookery must address their properties. He notes that cellulose, lignin, and woody fibre are chemically similar, yet physically diverse. This observation leads to a discussion of how heat and moisture affect different plant tissues, and why some vegetables soften while others remain tough. Williams's approach is consistently comparative: he moves from animal to vegetable, from theory to kitchen practice, and from the microscopic to the edible.
Readers approaching The Chemistry of Cookery should expect a work that is part textbook, part memoir, and part polemic. Williams writes for an audience that includes both the scientific amateur and the practical cook, and he assumes a willingness to follow detailed arguments. The book rewards those who read it sequentially, as later chapters build on earlier principles. It is not a collection of recipes but an inquiry into the reasons behind culinary practice, and its value lies in the questions it raises as much as in the answers it provides.
In that old Victorian cookery, I recall the careful chemistry of boric acid for keeping meat—a precise, trusting faith in preservation. It reminds me, oddly, of a simpler volume, The Perdue Chicken Cookbook — A Reader’s Guide, where the same quiet reverence for technique hums beneath homey recipes. Both taught me that patience, not fuss, makes a meal honest.
