KITCHEN PRACTICE 2 — Bias-Cut vs. Straight-Cut, Stir-Fried
==================================================
Chapter: Chinese Cookery 2 — The Cleaver & Chinese Knife Skills

TASK
----
Cut one portion of a vegetable (carrot or a similar firm vegetable)
on the bias, and a second, equal portion straight down. Stir-fry
both for the exact same short amount of time and compare how evenly
each portion cooked through.

WHAT TO DO
----------
1. Take two equal portions of a firm vegetable like carrot.
2. Slice the first portion at a clear angle — on the bias — into
   pieces of a consistent thickness.
3. Slice the second portion straight down, at the same thickness
   setting, so both portions use an identical thickness as the one
   real variable being tested.
4. Heat a small amount of oil in a pan or wok until hot, and add
   both portions at the same time, keeping them in separate areas of
   the pan if possible so you can tell them apart.
5. Stir-fry both for a short, fixed amount of time (60-90 seconds is
   enough for this comparison), then remove and taste a piece from
   each portion.

WHAT TO EXPECT
--------------
- The bias-cut pieces should taste more evenly cooked through — a
  consistent, tender-crisp texture from edge to centre.
- The straight-cut pieces, at the same thickness, may show a
  slightly less cooked, firmer centre compared to their own edges —
  a real, if sometimes subtle, difference in how evenly the heat
  penetrated in the same short cook time.
- If the difference is hard to detect at this small scale, try the
  same comparison with a genuinely thicker cut of vegetable, where
  the effect becomes easier to taste and see.

WHY THIS WORKS AS AN ANSWER
----------------------------
This is a direct, tasteable test of the chapter's own central claim
about bias-cutting — that it's a functional choice about surface
area and cook time, not a stylistic flourish. Holding the cook time
and thickness setting constant between both portions isolates the
angle of the cut as the one real variable, making any difference in
how evenly each portion cooked a genuine result of the cutting
technique itself.
