KITCHEN PRACTICE 3 — Comparing a Braise's Simmer to Confit's Fat Temperature
==================================================
Chapter: French Cookery 7 — Braising & Confit

TASK
----
Using a thermometer, compare a braising liquid's real simmer
temperature against confit fat held at 90°C. Note the visible
difference in how each one moves at its own correct temperature.

WHAT TO DO
----------
1. Bring a pot of water (or an actual braising liquid, if you have
   one going) to a genuine bare simmer — small, occasional bubbles.
2. Check its temperature with a thermometer. It should read close to
   100°C (212°F), or slightly below at a true bare simmer.
3. Separately, heat a pot of oil or fat, checking the temperature
   continuously with a thermometer, until it reaches exactly 90°C
   (195°F).
4. Hold the fat at that temperature for a minute or two, watching it
   closely.
5. Compare the two side by side: how much visible movement each one
   shows at its own correct, intended temperature.

WHAT TO EXPECT
--------------
- The simmering water should show real, if gentle, visible movement
  — small bubbles rising steadily to the surface.
- The 90°C fat should show little to no visible movement at all —
  it should look almost still, with maybe the faintest shimmer, a
  genuinely different visual signature from the simmering water even
  though it's not dramatically cooler.
- If your 90°C fat is bubbling or moving noticeably, it's worth
  checking your thermometer's accuracy or reducing the heat further
  — real confit fat genuinely shouldn't look like it's simmering.

WHY THIS WORKS AS AN ANSWER
----------------------------
The roughly 10°C gap between a braise's simmer and confit's own
correct temperature sounds small on paper, but it produces a
genuinely different visual and physical result — this exercise
makes that difference concrete rather than abstract, giving you a
real reference point for judging confit's own heat by sight in
future, without needing a thermometer in hand every single time.
