Most cooking problems have simple solutions. Here are seven of the most common mistakes home cooks make — and exactly what to do about them.
1. Not seasoning pasta water
Pasta water should taste like the sea. Not salty, but definitively seasoned. Plain pasta water produces bland pasta, no matter how good your sauce is. Use at least a tablespoon of salt per litre of water.
2. Cooking in a cold pan
A cold pan means food steams rather than browns. Always preheat your pan over medium heat for at least a minute before adding oil, and add oil just before your ingredients. The exception: when rendering fat, like bacon or guanciale — start cold to render slowly.
3. Overcrowding the pan
Too much food in the pan drops the temperature, and again — everything steams instead of browning. Cook in batches. The extra time is worth it for the Maillard reaction you'll get: that golden, complex, deeply savoury crust.
4. Tasting only at the end
Seasoning is built in layers. Taste as you cook — at every stage. A pinch of salt added to the onions at the start is not the same as salt added to the finished dish. Develop the habit of tasting constantly.
5. Discarding pasta water
The starchy water left over from cooking pasta is liquid gold. It emulsifies sauces, loosens thick ragùs, and saves the day if your sauce is too thick or too oily. Always scoop out a cup before you drain.
6. Resting meat insufficiently
Meat needs to rest after cooking — the juices redistribute as it cools slightly. A chicken breast needs 5 minutes; a roast chicken needs 15–20 minutes. Cut too soon and all those juices end up on the board, not in the bite.
7. Following recipes too rigidly
Recipes are guidelines, not laws. A recipe that says "cook for 10 minutes" is written for a specific stove, specific cookware, and a specific altitude. Learn to read your ingredients and your pan instead of the clock. When does the onion smell sweet? When is the edge of the steak starting to turn grey? Cook by observation, not just by timing.
