Cooking is all about trial and error. Professional chefs learn kitchen rules of thumb the hard way: whether being shouted at, burnt, cut or reduced to sweat-drenched wrecks drowning in tickets, they learn never to make the same mistake twice and all that suffering makes them better chefs in the long run, hopefully.
The chefs of Reddit were aksed to share some of the unwritten rules they’ve learnt over years in hot, frenetic kitchens. See their cooking commandments below, which can be applied to both professional and home kitchens:
Chefs share 17 cooking commandments
Wear shoes. Dropping a chef knife blade down or a boiling pot of noodles on your bare feet is no good.
Clean up as you go.
Stoves come equipped with low and medium settings for a reason.
Use weight whenever possible. One cup of flour is not always the same as one cup of flour, but 300g of flour is always 300g of flour.
Seafood. When you think it’s done you overcooked it.
Great cooking is a three-legged stool: part quality ingredients, part recipe, part technique. If you can accomplish all three your dish will be successful.
Taste. Your. Food.
Don't be afraid of fat/sugar/salt, etc. because they're "unhealthy." That's the flavour. Unless you have a dietary restriction, just don't overeat and you'll be fine.
A dull blade is more dangerous than a sharp blade.
