All-Clad Copper Core Saucier: Review

The verdict first

This is an excellent pan that most people should not buy. Its advantage over a five-ply aluminum-core saucier is response time, and response time only changes the outcome in a specific class of cooking: emulsified sauces, custards, anything held in a narrow temperature band where a few seconds of overshoot is the difference between finished and ruined.

If you make hollandaise, beurre blanc, crème anglaise or lemon curd with any regularity, this is the best tool on this site for it. If you do not, you will pay a large premium for a property you will never exercise, and the Made In or Misen saucier will give you the same results.

What it publishes

Five-ply construction with a copper core between two aluminum and two stainless layers. Oven and broiler safe to 600F. Compatible with any stovetop including induction. Handwash only. Limited lifetime warranty. Handcrafted in All-Clad's Canonsburg, Pennsylvania factory. The exposed copper band around the exterior is the line's visual signature.

Why copper actually matters here

Copper conducts heat faster than aluminum, which in practice means the pan both gains and loses heat more quickly. The second half is the useful one. When a butter emulsion approaches its break point and you pull the pan off the burner, an aluminum-cored five-ply keeps delivering stored heat into the sauce for several seconds. A copper-cored pan stops sooner.

That is a small window and it is exactly the window in which these sauces fail. It is also why the advantage is invisible almost everywhere else: in a pan of soup, in rice, in a reduction you are actively watching, nothing is decided in three seconds.

The rounded saucier walls compound the benefit. You get complete whisk contact and fast thermal response in the same pan, which is precisely the combination that difficult sauces want. The shape argument is made in full in saucier vs saucepan.

How long will it last?

As long as any All-Clad, which is to say indefinitely if you do not thermally shock it. Construction, rivets and warranty are the same as the rest of the range, and All-Clad's handle joins are the best-evidenced in the category thanks to America's Test Kitchen's concrete-strike abuse protocol.

The copper band is the one thing that ages visibly. It will darken and spot within months, and it responds to polishing if that bothers you. It is cosmetic and has no effect on cooking. We would argue it is useful: it is an honest record of how the pan has been treated, in a category where everything else hides its history.

The warranty is All-Clad's standard limited lifetime: defects in material, construction or workmanship covered; normal wear, discoloration and warping from high heat or heating empty, misuse, abrasive-cleaner damage and commercial use excluded; US and Canada only. Note that the copper band's discoloration falls squarely under the normal-wear exclusion, and reasonably so.

The honest downsides

The price. This is the most expensive pan on the site and there is no argument that makes it cheap. The value case rests entirely on whether you cook the narrow category of dishes it is better at.

Handwash only. On a pan you will use for custards and reductions, which are among the more tedious things to clean.

600F, not 800F. Made In and Heritage Steel publish higher. At this price that is a legitimate complaint, though 600F is ample for anything you would do in a saucier.

Who should skip it

Anyone who does not make emulsified sauces. Anyone buying their first saucier, who should find out whether they like the shape at a third of the cost. Anyone who wants a dishwasher-safe pan. And anyone choosing between this and a second, more versatile pan — a saucier this good is a poor substitute for owning a stockpot you do not have.
