Watery scrambled eggs

The water was inside the egg

A raw egg is protein molecules floating separately in water. As it heats they unfold and link into a loose three-dimensional network, and that network traps the water. That is a soft set, and it is what good scrambled egg is.

Heat it further and the network keeps contracting. Past a point it squeezes the trapped water out, the curds tighten and shrink, and you get firm rubbery pieces sitting in liquid.

This is the same process — syneresis — that makes a custard split, a quiche weep and a cheesecake crack. Once the water is out it does not go back in.

What is causing it

• Too much heat. The dominant cause. Scrambled eggs want a low to medium heat and patience.
• Cooked too long, or left in the pan. They carry on cooking off the heat. Take them out while they still look slightly underdone.
• Salted too early. Salt dissolves egg proteins and, given time, makes them hold water less well. Salting several minutes ahead is worse than salting in the pan.
• Milk or cream added in quantity. Added liquid has to be held by the same protein network, and any that is not held ends up in the pan.
• Kept warm. A pan of scrambled eggs held for service will weep however carefully it was cooked.
• Cooked in a thin pan with hot spots, so parts overcook before the rest has set.

Cooking them so they hold together

1. Beat the eggs properly — thoroughly enough that there are no streaks of white. Uneven mixing gives uneven setting.
2. Use a heavy pan on a low to medium heat, with butter.
3. Stir constantly with a spatula, scraping the base and folding the setting egg back through. Small curds hold water better than large ones.
4. Take the pan off the heat every so often and keep stirring. Residual heat does a surprising amount of the cooking.
5. Stop while they still look glossy and slightly loose. They will finish on the plate.
6. Season in the pan at the end, not several minutes before.
7. Serve immediately. Holding them is what undoes all of the above.

Additions, and what each does

Nothing at all

Egg and butter. The French approach, and the least likely to weep.

A splash of milk

Softens the set slightly. More than a splash and the excess ends up in the pan.

Cream, off the heat at the end

Stops the cooking and enriches. Better than cream at the start.

A knob of cold butter at the end

Same effect — it drops the temperature and halts the set.

Crème fraîche or soft cheese

Adds fat, which interferes with the protein network and gives a softer, more forgiving curd.

Safety

How eggs and dairy should be stored, and which eggs are suitable raw or lightly cooked and for whom, are food-safety questions rather than culinary ones. Follow current Food Standards Agency guidance.
