Dry chicken breast is the most common cooking failure in home kitchens — and the cause is almost always the shape of the breast, not the cooking method.

A standard chicken breast is a wedge shape: 3 to 4cm thick at the centre, tapering to 5 to 8mm at the edges. Heat conducts at the same rate across the entire surface. The thin edges reach 74°C in 3 to 4 minutes. The thick centre requires 8 to 12 minutes. By the time the centre is safe, the edges have been at 80 to 90°C for several minutes — dry, rubbery, and significantly shrunken.

Butterflying solves the geometry. A horizontal cut through the thick centre, opening the breast flat, reduces the maximum thickness from 3 to 4cm to 1.5 to 2cm across the entire breast. Every point now reaches the safe temperature at approximately the same time. Total cooking time reduces from 8 to 12 minutes to 4 to 6 minutes. Less time at heat means less moisture expelled.

The full pan contact of the flat butterflied surface also produces even Maillard browning across the entire breast — not the partial browning of a rounded, uneven surface.

Save this and butterfly every chicken breast before cooking.

Two steaks at identical temperatures produce completely different results if they have different thicknesses — and the reason is the rate of heat conduction.

A 1cm steak at 200°C pan heat has its centre approximately 5mm from both surfaces simultaneously. Heat reaches the centre from both sides in 60 to 90 seconds. By the time the exterior is approaching Maillard temperature, the centre has already exceeded the target internal temperature. A thin steak physically cannot achieve a deep crust with a rare or medium-rare interior — the heat travel distance is too short.

A 3 to 4cm steak has its centre 15 to 20mm from the nearest surface. At the same pan temperature, heat takes 5 to 8 minutes to conduct to the centre. During this time, the exterior can develop a full Maillard crust, while the centre remains at or below the target temperature. The thermal gradient — hot exterior, cool interior — is the property that allows simultaneous crust and rare interior.

For very thick steaks (5cm plus), even the standard sear cannot control the result precisely enough. The reverse sear — low oven to internal temperature, then aggressive pan sear — decouples the interior cooking from the surface crust formation.

Save this and match your cooking method to the thickness of the steak.
