Kelvin: cooking by temperature

Editorial interest 84/100 Selection signal · not a rating of the site

A cooking app that maps Chinese dietary therapy’s hot-to-cold food classification onto a Kelvin scale, then builds meals around it.

Landing page captured for the 2026-08-31 issue.

Why it surfaced

Kelvin turns an unusual theory into a concrete kitchen interface: choose a temperature band, meal size, and bodily pattern, then browse or randomly roll from a recipe deck. The site is unusually candid about its limits, calling itself a cooking app rather than medical advice and noting where ingredient sources disagree.
