You want to eat it while it’s hot- but fight the urge to cut every meat and serve dishes just after cooking them. Chicken, beef and all need to rest for a while to let their juices redistribute after cooking. Even brownies need to hang out in the pan for a bit! It will be much easier to slice and get out of the pan.
Having a sharp knife is more important than you think. Some might be afraid to use sharp knives but the dull ones are in fact more damaging. Using a sharp knife also makes cooking more enjoyable.
You love what you’re making, but you need to leave it be without poking and flipping too often! Did you know meat only needs to be flipped once? Just once and you can have a delicious, juicy piece of meat.
This is extremely common if you’re baking something. Sometimes you skip steps in recipes thinking that it’s not important to follow, like putting cookies in the oven before the oven is fully pre-heated to the specified temperature. This is very important. Always preheat your oven and always listen to the recipe.
