Every dish is five dials and a thermometer.
Salt, fat, acid, heat, time. Learn what each one actually does to food and recipes stop being instructions you obey — they become suggestions you can argue with, and eventually skip. Nothing on this site is a recipe. Everything on it is the reason recipes work.
Install it on any device
This whole site installs as an app on a phone, tablet or computer: its own icon, its own window, and every page, calculator and timer working with no connection at all. Handy on a laptop propped on the counter as much as a phone in your apron.
Mac
In Safari, choose File → Add to Dock (macOS Sonoma or later). In Chrome or Edge, click the install icon at the right of the address bar. It opens in its own window and lives in Launchpad.
Windows, Linux & Chromebook
In Chrome or Edge, click the install icon at the right of the address bar — or in Edge, … → Apps → Install this site as an app. It goes in the Start menu or app launcher, and can be pinned to the taskbar.
iPhone or iPad
In Safari, tap Share, then Add to Home Screen. There is no install button on iOS — this is the route, and it works properly once done.
Android
Use the button above, or Chrome’s menu → Install app.
Firefox can’t install web apps on any computer, but the site still works offline in it once you’ve visited.
The numbers you will want first
Three pages, in the order they build
Heat
The temperature ladder drawn to scale, from a fridge-cold 40 °C to the smoke point — plus a calculator that tells you what to pull food off at, given how it carries over.
Open Heat → TwoKitchen
Two calculators that replace most of a cookbook: how much salt, in three modes, and ten ratios you can scale by typing any single quantity.
Open Kitchen → ThreeLearn
Ten techniques in the order they build on each other, the five dials underneath them, five dishes to drill them on, and the nine tools you actually need.
Open Learn →Timers
They keep running as you move around the site and survive a reload — a strip appears under the header wherever you are.
