25. You use inferior ingredients.
This is an important point because it’s the linchpin of great cooking: Good food begins and ends with the ingredients. The dishes you cook will only be as mediocre, good, or superb as the ingredients you put in them. As a rule, we recommend using high-quality ingredients whenever available and affordable.
Always shop for the best ingredients. They’re the foundation of good cooking and why we strive not to make the mistakes described here. Choose top-notch produce, meats, and cheeses, and protect them as you would anything else precious―handle with love, respect, and care so you can be a steward of the joys of great food. Your cooking will invariably turn out better.
