“It was bad” is understandable after a disappointing dinner, but it gives the next version nowhere to start. Try narrowing it down once the frustration has passed.
Was the rice hard, the sauce too salty, or the vegetables crowded on the tray? Those observations suggest different changes. Keep the note short and practical, and avoid changing every part of the recipe in response to one problem.
Some mistakes can be adjusted while cooking; others are better accepted as information. Burnt garlic and food with an unsafe storage history are not challenges that need a clever rescue.
Choose a familiar meal next if you need a break. Learning is easier when every dinner is not a referendum on whether you can cook. One specific correction, used later, is already a useful result from an imperfect evening.
