The Science
Four ingredients and a dial, in proper detail: what milk is made of, the three chemically different ways to coagulate it, and the enzymes and bacteria that do the rest of the work.
Milk A suspension of protein particles and fat droplets in sugar water. Including why the casein micelle diagram in older books has been superseded — and why the new picture is more useful at the bench. Explore →
Coagulation The fork the whole craft hangs off. Acid takes the charge away and gives a precipitate; rennet cuts one specific bond and gives a network; heat-acid recruits the whey proteins the other two throw away. Explore →
Rennet Animal, FPC, microbial and plant — not interchangeable. Why vegetable rennet turns bitter in a long-aged wheel, what IMCU means on the bottle, and why the option with the worst image is arguably the best. Explore →
Cultures Mesophilic versus thermophilic is the substitution that ruins the most wheels. Plus the organism that makes Emmental’s holes — and why its flavour and its gas are two outputs of one reaction. Explore →
The Curd Cut, heal, stir, cook, wash — five hands on one dial. Why cloudy whey is your yield leaving the vat, and why washing the curd invented Colby by accident. Explore →
Salt & pH Salt is a brake, not a seasoning. And a brine with no calcium in it will pull the mortar out of your cheese — the defect people meet, blame on technique, and never diagnose. Explore →
Ripening Controlled decomposition. Proteolysis for flavour and texture, lipolysis for sharpness — and the two completely different crystals that everyone calls the same thing. Explore →
Rinds & Moulds A rind is a living community, not packaging. The four organisms you invite on purpose, what wax and bandage trade away — and which fuzz means throw it out. Explore →
Melting Calcium cross-links explain everything. Halloumi and feta both refuse to melt for opposite reasons — and sodium citrate, which makes anything melt smoothly, is the basis of processed cheese. Explore →
