About

Bean to bar, backed by the science.

JayArr Chocolate is a workshop for people who want to actually understand craft chocolate — not just admire it. Every tool and guide here is built to turn scattered folklore into something you can measure, taste, and repeat.

The approach

Most chocolate advice is handed down as lore — a temperature someone's grandmother swore by, a rule with no reason behind it. We take a different route. Every calculation, timeline, and recommendation on this site is grounded in a knowledge synthesis built from eleven authoritative sources, cross-referenced and attributed so you can trace any claim back to where it came from.

That means when the Tempering Station tells you 31°C, or the Melanger Guide says taste at hour eight, there's a citation behind it — Beckett, Afoakwa, Nanci, Dandelion. The goal isn't to be authoritative for its own sake. It's to get you to genuinely good chocolate, faster.

From the JayArr kitchen

Chocolate is one obsession of several. The same evidence-first approach runs through everything we make — coffee, pizza, and bread all get the same treatment.
