Poach the protein in gently simmering water or master stock until just cooked through. Transfer immediately to an ice bath and hold until fully cold. The skin — if present — should be taut and gelatinous to the touch; the flesh firm but yielding, not fibrous. Remove, drain thoroughly, and refrigerate until needed. Do not proceed if the flesh feels dry or stringy: overcooked protein cannot be corrected at cold service.

No more than 20 minutes before service, slice the cold protein across the grain to a maximum of 2 mm. Thin slices lie flat, integrate with the sauce at the cut face, and read as elegant on the plate. Thick slices are dense and resistant; there is no heat to open them at the table.

Smack the cucumber firmly with the flat of a cleaver along its length until it splits. Tear by hand into irregular pieces, salt lightly, and allow to drain in a colander for 10 minutes. Pat dry. The rough, uneven surfaces are deliberate: they hold cold sauce where a smooth cut face would not.

Grind the Sichuan pepper immediately before use — the floral volatiles dissipate rapidly; pepper ground in advance will contribute heat but not fragrance. Assemble the red oil sauce by combining chilli oil, soy sauce, sesame paste, Sichuan pepper, vinegar, sugar, and garlic in a bowl. Whisk to a unified, glossy sauce. This is where the dish lives or dies: taste the assembled sauce alone, at room temperature. It must taste slightly aggressive — sharper, saltier, and more intense than the finished dish should be. The protein and vegetable will absorb salt and dilute the sauce as they are dressed. A sauce that tastes correct before dressing will be underseasoned on the plate. Adjust acid, salt, or heat until the sauce reads forceful.

Dress the sliced protein and smacked cucumber separately, no more than 20 minutes before service. Toss each preparation in just enough sauce to coat every surface; excess sauce will pool on the plate and dilute as it draws moisture from the ingredient. Both preparations should smell of chilli oil and sesame, with a restrained floral Sichuan pepper note — more restrained than a hot preparation; this is correct at room temperature.

Allow the dressed preparations to rest at room temperature for 20 minutes if they have been refrigerated. Plate with deliberate visual intention: distinct colours, considered symmetry, height variation. Cold dishes are plated with more care than hot dishes; the arrangement communicates the attention of the kitchen. Taste a final time immediately before service — refrigeration dulls flavour — and adjust seasoning if necessary. The first bite should deliver the sauce character clearly; subsequent bites should show the integration of sauce and ingredient.
