Method
- Diagnose before you touch it: grainy specks in a thin liquid means the yolk cooked, a clear oil layer over sludge means the emulsion was overloaded, a stiff dull paste means it only got cold.
- For a cold seize, stand the pan in water at 45C (113F) and whisk until it flows again; adding anything here just dilutes a sauce that was never broken.
- For an overloaded emulsion, put 15 ml of boiling water in a clean warm bowl and whisk the broken sauce into it a teaspoon at a time until it takes, then in a thread; the fresh water phase gives the droplets somewhere to sit.
- For a cooked yolk, strain out the specks, beat a fresh yolk with 15 ml of cold water off the heat, and whisk the strained sauce into that drop by drop; the grains themselves never come back.
- For a broken butter sauce, drop the pan into the ice bath until it is below 60C (140F), then whisk 30 ml of cream or a 20 g cube of cold butter in a clean pan and rebuild the broken sauce into it.
How to tell it is going right
This dish has no standard of its own yet. It is judged on the techniques it exercises: checked at the pan, while there is still something to be done about it.
Building an emulsion 40 recipes
- It visibly thickens as the fat goes in, heavier and more opaque than either part was alone, which is the emulsion announcing itself.
- At no point is there a pool of free fat sitting ahead of the work: fat went in no faster than it disappeared into the body.
- Glossy and homogeneous, with no slick floating on top and no visible droplets standing apart in it.
- It clings: coating what it is put on and holding a line, rather than running off and splitting into a puddle at the plate’s edge.
- It survives standing: minutes later there is no ring of weeping liquid underneath and no film of fat breaking out on the surface.
Where it goes wrong The fat went in faster than the shear could break it up, or the temperature drifted out of the range the method needs: it breaks into grease over a thin liquid, and whisking the broken thing harder does nothing. The rescue is a fresh base, with the broken sauce worked into it slowly, as if it were the fat.
Deglazing & pan sauces 49 recipes
- The pan still holds its fond. Nothing has been rinsed, wiped, or soaked, and the browned layer is intact on the floor.
- Excess fat was poured off first and the browned layer left behind; the fat is not the flavour and a sauce carrying all of it will not come together.
- The liquid went into a still-hot pan and the floor came clean: scraped while it bubbles, the base goes from stuck brown to bare metal and the sauce darkens as it takes it up.
- The fond was brown and not black. A burnt floor dissolves into bitterness that cannot be seasoned out, and is better washed away than deglazed.
- Reduced first and seasoned afterwards, tasted at the consistency it will be served at rather than at the start.
Where it goes wrong The pan was left to stand and go cold before anybody came back to it. Cold fond will not dissolve, so the scraping lifts nothing, and the sauce arrives thin and pale with the flavour it was supposed to carry still welded to the metal.
