Reading Oil Heat with Chopsticks

Stand a dry wooden chopstick in the oil. The bubbles tell you the heat. No thermometer needed.

Difficulty: 2
Heat: high

Key Points

150C: a few slow bubbles. 170C to 180C: steady fine bubbles from the whole tip. 190C: fast, noisy bubbles.

Common Failures

A wet chopstick bubbles too much and reads hot. A bamboo skewer is too thin to read well.

Do this

Dry a wooden chopstick well. Stand it on the bottom of the pot. Watch where the bubbles start and how fast they rise.

Why it works

Wood holds a little water. Hot oil turns that water into bubbles. Hotter oil makes more bubbles, faster.

When to skip it

Skip it for candy or oil above 200C. There a real thermometer is safer.
