Food often tastes better slightly cooled than piping hot
#0062 Food & cooking
Fact rank
B
The mechanism by which warmth strengthens sweetness was confirmed in research (primary). But it was measured only up to 35°C; no source confirms that excessive heat dulls taste or that temperature affects umami in the same way; and "tastes better" is partly a matter of preference, so B
Wow rank
A
The opposite of the belief that food is best piping hot
Usefulness
A
You can try it just by waiting a moment before eating

Food often tastes sweeter and more savoury once it has cooled a little than when it is piping hot.
Why
The tongue sensor for sweet and umami tastes (TRPM5) works more strongly the warmer it is, between 15 and 35°C. Food that is too hot, though, is felt mainly as heat and cannot be savoured.Evidence
Primary Abstract of Talavera et al. (2005, Nature). TRPM5, a channel with a key role in perceiving sweet, umami and bitter tastes, responds more strongly as temperature rises between 15 and 35°C. Warming also strengthens the sweet-taste nerve response, explaining enhanced sweetness at higher temperatures link
Secondary Tottori Prefecture. Oleic acid melts at a low 16°C. When two beef fats were held at 40°C for 10 minutes, the one higher in oleic acid (55.8%) began to melt, while the lower one (48.8%) turned white and solid after an hour link
Poster's experience The poster's own experience: food tastes better slightly cooled than piping hot
Notes and limits
Exceptions are dishes whose fat sets and turns waxy when too cool (fatty meat, for example) and foods like fried food whose texture suffers as they cool. Even among beef fats, the melting temperature depends on the oleic acid content. No study measuring the best eating temperature for each dish was found. Japanese Wikipedia's "Taste" (味覚) article has only one sentence saying taste perception varies with temperature.
