Poaching Oysters in Their Own Liquor

What It Is

Gently warming shucked oysters in their own strained liquor just until the edges firm — seconds to a minute, never a simmer.

Why It Matters

Oysters seize and toughen fast with heat. A bare poach sets them enough to hold under a grill while keeping them plump, and the liquor itself becomes a concentrated seasoning you reuse in the sauce.

How to Execute

• Strain all the liquor through a fine sieve to remove shell fragments.
• Warm it over very low heat; slip the oysters in and watch for the edges to just ruffle and firm.
• Lift them out immediately; reserve a measured amount of the liquor (here 30 ml) for the sabayon.

Common Mistakes

• Letting the liquor simmer — rubbery oysters.
• Not straining — grit in the dish.
• Overcooking now and again under the grill — they only need one gentle pass.
