Why did hollandaise or bearnaise broken turn out this way?

Hollandaise is an emulsion where clarified butter is suspended in a water phase stabilized by lecithin from egg yolks. If the sauce overheats above 160 degrees F, the yolk proteins coagulate and can no longer stabilize the emulsion. Adding butter too fast overwhelms the emulsifier capacity. A fresh yolk provides new lecithin to rebuild the emulsion from scratch.

What should I do if hollandaise or bearnaise broken is still not fixed?

Use an immersion blender to re-emulsify the broken sauce directly in the pot for 10 seconds. Add 1 tablespoon cold heavy cream and whisk vigorously for 30 seconds, which sometimes restores a mildly broken sauce.

How can I prevent this problem next time?

Keep the water bath or double boiler below 160 degrees F; you should be able to touch the bottom of the bowl without burning. Add clarified butter in a very thin stream, no faster than 1 tablespoon every 10 seconds, whisking constantly.

Hollandaise or Bearnaise Broken

Your hollandaise or bearnaise has separated into a greasy, curdled mess because the egg yolk emulsion broke from overheating or adding butter too fast. A fresh yolk or cold water can re-emulsify it.

The fix

Pin it

Tap a step to check it off.

1 place 1 fresh egg yolk in a clean bowl with 1 tablespoon warm water and whisk until frothy
2 very slowly drizzle the broken sauce into the yolk while whisking constantly, about 1 tablespoon at a time
3 once re-emulsified, season with a few drops of lemon juice and serve immediately

If it's still wrong

Use an immersion blender to re-emulsify the broken sauce directly in the pot for 10 seconds.
Add 1 tablespoon cold heavy cream and whisk vigorously for 30 seconds, which sometimes restores a mildly broken sauce.

Prevent next time

Keep the water bath or double boiler below 160 degrees F; you should be able to touch the bottom of the bowl without burning.

Notes

Why this works

Hollandaise and bearnaise are oil-in-water emulsions. Each tiny droplet of clarified butter is surrounded by a film of lecithin (a phospholipid from egg yolk) that keeps the fat suspended in the water-based lemon juice or vinegar. The yolk proteins also unfold in gentle heat to create a network that thickens the sauce.

When the sauce overheats, those same proteins coagulate into tight clumps (you see this as curdling), and they can no longer coat the fat droplets. The butter pools together and separates. A fresh egg yolk provides a new supply of lecithin and undenatured proteins. By drizzling the broken sauce slowly into the fresh yolk, you are essentially remaking the emulsion from scratch, using the broken sauce as your butter source. The slow addition is critical because each tablespoon of fat needs time to be broken into tiny droplets and coated with emulsifier before more is added.
