Tools
Learn the science, then use it. Every tool here lives directly on the article that explains its mechanism -- no separate app needed yet, just the same real chemistry made interactive. Eventually these are meant to become the seed of a free companion app for using them hands-on in the kitchen.
🫧 Baking Powder ⇆ Baking Soda Converter
Convert between baking powder and soda + cream of tartar, based on the standard ratio.
🍬 Sugar-Stage Altitude Calculator
Get every candy stage's target temperature corrected for your actual altitude.
❄️ Salt & Ice Temperature Estimator
Enter your salt and ice weights, get the real freezing-point-depressed brine temperature.
🍫 Chocolate Tempering Tracker
Pick your chocolate type, get the melt/cool/rewarm targets as a checkable list.
More on the way
New tools get added as their mechanism gets a full article, not before -- next candidates are a hydration/baker's-percentage calculator (Structure) and an egg-substitution picker (Substitutions & Alternatives).
