How do I poach things without them disintegrating?

Poaching has one variable that matters and everything else is detail. Get the temperature right and delicate things survive; get it wrong and they fall apart regardless of technique.

Safety

Step by step

1. Learn what the surface should look like.Steam rising, the odd bubble breaking, the surface barely trembling. That is 70 to 80°C. If it is bubbling steadily it is too hot, and you are boiling rather than poaching.
2. Bring it up and then turn it down.Heat the liquid to a simmer, then reduce until it stops bubbling before adding anything. Trying to hold a low temperature from cold takes forever.
3. Flavour the liquid.Poaching in plain water leaches flavour out. Stock, wine, aromatics, bay, peppercorns, lemon. What goes in the liquid ends up in the food.
4. Use enough liquid to cover.Anything sticking out cooks unevenly. Just covered is right — much more than that dilutes the flavour and takes longer to come to temperature.
5. Add acid for eggs.A splash of vinegar helps the white set faster and hold together. Use the freshest eggs you can — an older white is looser and spreads.
6. Create a vortex for eggs, not for anything else.Swirling the water helps an egg white wrap round itself. Do not do it with fish or fruit, where the movement is exactly what breaks them apart.
7. Lower things in gently.A slotted spoon or a spatula. Dropping fish into hot liquid breaks the flesh and splashes.
8. Poach fish barely at all.It is done when it turns opaque and flakes with light pressure — often only a few minutes. Fish continues cooking in the residual heat, so take it out slightly early.
9. Poach chicken off the heat.Bring the liquid to a simmer, add the chicken, cover, turn the heat off and leave it. Gentle residual heat gives noticeably more tender meat than active cooking.
10. Check chicken with a thermometer.75°C in the thickest part. Poached chicken looks pale and done before it is, so this is not the place to judge by eye.
11. Poach fruit in syrup, not water.Sugar in the liquid keeps the fruit firm by balancing the osmotic pressure. Fruit poached in plain water goes soft and collapses.
12. Cool fruit in its own liquid.Leave it to cool in the syrup rather than lifting it out hot. It keeps absorbing flavour and holds its shape better.
13. Keep and reuse the liquid.Chicken poaching liquid is stock. Fruit syrup is a cordial base. Strain and keep it rather than pouring away the flavour you just made.

Tips

• Barely trembling, occasional bubble. If it is bubbling steadily you are boiling and delicate things will break up.
• Poach chicken with the heat off. Bring to a simmer, add it, cover, switch off, and leave it — far more tender.
• Poach fruit in syrup, never plain water. Sugar is what holds the shape.

Common mistakes

• Letting the liquid boil — The agitation physically breaks fish and eggs apart, and it makes chicken tighten and go stringy.
• Poaching in plain water — Flavour moves out of the food into the water. Flavour the liquid and it moves the other way.
