Broken hollandaise has one especially useful diagnostic split: separated emulsion versus cooked yolk. Both look wrong, but only one is realistically recoverable. Identify whether you have free butter or actual egg curds before you add water, a new yolk, or more heat.
Symptom matcher
Which one looks most like yours?
Small visual differences can point to very different causes.
Check whether there are actual egg curds.
Stop heating and inspect the yolk solids.
Warm a small portion gently.
Whisk a few drops of water into a test spoonful.
Review hold time and temperature.
Right now
Can it be saved?
Usually if it separated without curdling; no if the yolks are visibly scrambled.
Limit: Re-emulsification fixes separation, not cooked egg protein. Continuing to whisk a curdled hollandaise does not reverse coagulation.

Get to the first clue faster
Answer one question at a time. The result comes from the same reviewed diagnosis data below.
Do you see curd-like or scrambled-egg solids?
The yolks have coagulated
Visible curds mean overheating; this is not a normal recoverable emulsion break.
Likely cause: The yolks or sauce became too hotIs there free butter or a greasy layer?
Did the separation begin while butter was being added?
Rebuild the emulsion and slow the butter
A break during butter addition strongly points to overwhelming the emulsion.
Likely cause: The butter was added faster than the emulsion could absorb itCheck water phase and holding temperature
If the butter addition was controlled, test a few drops of water and review how the sauce was held.
Likely cause: The emulsion became too concentratedCheck temperature drift
If there is no obvious free-butter layer, the failure may be a too-cold or holding problem.
Likely cause: The sauce drifted out of its stable range during holdingDiagnosis
Check the likely causes
Start at the top, but skip anything that clearly does not match your batch. Evidence labels describe the support for each cause, not a fake probability score.
The butter was added faster than the emulsion could absorb it
The sauce becomes thin and greasy while butter is being added, but there are no scrambled-egg curds.
If separation began during a fast pour of butter, this cause is a strong match.
Start a fresh small emulsion with water or lemon juice, or with a fresh yolk, then whisk the broken sauce into it slowly.
Add butter in a thin controlled stream while whisking continuously, especially at the beginning.
The yolks or sauce became too hot
The sauce looks grainy or lumpy like fine scrambled eggs rather than simply oily.
Inspect the solids. Distinct curds or a scrambled-egg texture indicate overheating rather than a merely broken emulsion.
Discard or repurpose; smooth hollandaise cannot be rebuilt from fully scrambled yolks.
Use controlled heat and remove the bowl from heat before the proteins over-set.
The sauce became too cold
The sauce thickens excessively or breaks after cooling rather than during initial butter addition.
Warm a small portion gently. If the texture relaxes and recombines without egg curds, low temperature was likely involved.
Warm very gently while whisking; some culinary-school methods use a warm-water or bain-marie correction.
Hold hollandaise warm, not hot and not chilled, and avoid long temperature swings.
The emulsion became too concentrated
The sauce becomes extremely thick before fat begins to pool, without signs of scrambled yolk.
Whisk a few drops of water or lemon juice into a small portion. If it smooths quickly, insufficient water is a strong clue.
Whisk in a small amount of water or lemon juice, or rebuild the emulsion in a clean bowl and incorporate the broken sauce gradually.
Keep the yolk mixture from reducing excessively and correct thickness with small measured additions of water.
The sauce drifted out of its stable range during holding
The sauce was initially smooth but separated after sitting before service.
Check how long and at what temperature the sauce was held, and whether it failed hot or after cooling.
If there are no curds, try a small water-based re-emulsification. If curds are present, start over.
Make hollandaise close to service and hold it in a controlled warm range rather than on direct heat.
Don't jump to conclusions
Common misdiagnoses
Kitchen science
What is actually happening?
Hollandaise is a fat-in-water emulsion stabilized largely by egg yolk components such as lecithin. Adding butter too quickly, losing enough water, or drifting too far in temperature can overwhelm that emulsion. Excessive heat is a separate failure: yolk proteins coagulate into curds and stop functioning as a smooth emulsifying phase.
Testing plan
What we plan to test
Planned tests are shown transparently and are never presented as completed results.
Hollandaise failure modes: butter rate, heat and water phase
Fast butter addition will cause a recoverable oily separation, while excessive yolk temperature will cause an unrecoverable curdled texture.
