30% to 40% of the heat and the temperature of boiling water are about 100 degrees. For example, if you put a piece of garlic, there will be small bubbles.

50% to 60% hot, about 150 degrees. At this time, the oil surface is turning around, and the garlic slices are wrapped in a lot of bubbles. The reaction between 60% and 50% is slightly larger.

70% to 80% of the hot oil level stops rotating, and smoke is emitted around 200 degrees.
