Why Some Dishes Taste Better the Next Day
You spend hours cooking a curry, have it for dinner and then put the leftovers in the fridge — but, to your surprise, those leftovers taste better the next day.
Why does this happen? There might be a few reasons.
Even after cooking stops, your food's flavors keep changing. Certain spices can be quite harsh when you first cook with them, but can become less harsh over time.
Flavors from different foods also keep mixing with each other. Spices, for example, might spread through a sauce and give it more flavor.
Other flavors might mix with the fat in a dish. Fat helps carry these flavors and keeps them on your tongue for longer, so the food tastes better.
Other changes happen too. Starchy foods can release more sugars, making dishes a bit sweeter. This sweetness can reduce the harshness of other strong flavors.
Some vegetables also become less bitter because of contact with air, while proteins in meat can break down over time, making the meat softer and giving it more umami.
Another reason food might taste better the next day is that many people taste their food while they're cooking it. So they're less "surprised" when they actually eat the finished meal — and they might not be very hungry anymore. This could make the food taste better the next day, especially if the cook saw other people enjoying it!
Of course, not all leftovers taste better the next day. Certain foods, like pasta or steak, are best enjoyed when they're first made.
But if you've made a nice soup or curry, try letting it rest for some time — and let science do its thing!
