Mandoline Slicing

Purpose

Make repeatable thin slices for an even cooking and setting endpoint.

Controls

The Gratin source specifies 2–3 mm waxy-potato slices. Do not rinse them afterward because the source relies on surface starch.

Process

1. Set the mandoline to the specified thickness and use its hand guard.
2. Slice potatoes uniformly and keep the slices unrinsed for assembly.

Failure Modes

Symptom	Likely cause	Corrective action
Thick slices remain firm	Slice thickness varied or exceeded the specified range	Reset the mandoline and check a slice before processing the full batch.
