Tempering, emulsion, bloom, seizing — the technique behind why chocolate behaves the way it does.
Seeding method and tabling method described as two distinct procedures, each with its actual temperature curve (melt, cool, work, reheat), and a single practical test — a palette knife dipped and set — to confirm Form V was reached.

Seeding method and tabling method described as two distinct procedures, each with its actual temperature curve (melt, cool, work, reheat), and a single practical test — a palette knife dipped and set — to confirm Form V was reached. No theory before the steps.
Cocoa butter's six crystal forms — I through VI — what each looks like and at what temperature it forms, and why Form V is the target: the snap, the gloss, the melt point just below body temperature. An explainer that earns its length.
Fat bloom versus sugar bloom: what each looks like under the surface, what causes each (unstable crystal form in one case, moisture condensation in the other), and whether a bloomed bar is safe to eat and temper from. A diagnostic piece written for someone holding a white-streaked bar.
Why chocolate seizes when a small amount of water hits it — the starch-and-sugar particle mechanism, why a large amount of liquid does not trigger the same effect, and how to recover a seized bowl by adding more liquid deliberately. Counter-intuitive and exactly right.
Ganache as a water-in-fat emulsion — what water activity means for shelf life, what fat crystallisation does to texture over time, and the two conditions (temperature shock and over-agitation) that cause a split. A comparison between a stable and an unstable ganache at the molecular level, briefly.
Dutch-process versus natural cocoa — the alkalising step, what it does to colour and flavour, and why substituting one for the other in a recipe that uses baking soda produces a flat result. A practical argument for reading the label before you shop.
Couverture (legally defined cocoa-butter content, temper required) versus compound coating (vegetable-fat substitutes, no temper needed) — a direct comparison of what each is made from, what it costs to work with, and where compound is the sensible choice. Valrhona and Callebaut named as the pastry benchmarks; CBE substitution explained plainly.
