How do I finish a dish so it tastes complete?

Restaurant food tastes different largely because of what happens in the last thirty seconds. Long cooking flattens acidity and volatile aromas, and adding them back at the end is what makes a dish taste vivid rather than merely cooked.

What you'll need

• Lemon or vinegar (optional)
• Butter or good olive oil (optional)
• Fresh herbs (optional)

Step by step

1. Taste properly before finishing.Off the heat, at serving temperature. This tells you which of the four things below the dish actually needs.
2. Add acid.Lemon, lime, vinegar, a spoon of yoghurt. Long-cooked dishes lose their brightness, and this is the most effective single addition.
3. Add fat off the heat.A knob of cold butter stirred into a sauce, a swirl of good olive oil over soup or vegetables. It adds body and carries aroma.
4. Add fresh herbs at the last moment.Parsley, coriander, basil, dill. Their aroma is volatile and disappears with cooking, so they go in as the pan comes off.
5. Add texture if everything is soft.Toasted nuts, breadcrumbs, croutons, seeds. Monotonous texture reads as a lack of flavour even when the seasoning is right.
6. Adjust the salt last, not first.After the acid and fat are in. They change how salty the dish tastes, so seasoning before them means seasoning twice.
7. Consider a contrasting cold element.Yoghurt on a curry, soured cream on chilli, a raw salsa on grilled meat. Temperature and texture contrast lift a heavy dish.
8. Finish just before serving, not in advance.These additions are volatile by nature. Ten minutes standing on the hob undoes most of the benefit.

Tips

• Keep a lemon and a decent vinegar within reach of the hob. Between them they rescue more dishes than any spice.
• Cold butter whisked into a hot pan sauce off the heat gives gloss and body — it is the classic finish and it takes ten seconds.
• Save a small amount of a fresh ingredient from the dish to add raw at the end. Cooked and raw versions of the same thing gives depth and brightness together.

Common mistakes

• Adding herbs at the start of cooking — Soft herbs lose their aroma entirely with heat. Hard herbs like rosemary and thyme go in early; soft herbs go in at the end.
• Finishing a dish and then letting it sit — Acid and fresh aromatics fade quickly. Finish it as it goes to the table.
• Adjusting salt before adding acid and fat — Both change how salty the dish tastes, so you end up seasoning twice and often over-salting.
