Get the right temperature for deep frying
Does your oil always seem to be the wrong temperature? A simple way to find out if your oil is hot enough is to use a bread cube.
If the bread browns in a minute, the oil is between 350 and 365 degrees, 40 seconds – 365 and 382 degrees, 20 seconds – 382 and 390 degrees.
Or, if you have one, you can use a thermometer. Just be sure that it is a metal thermometer designed for deep fryers.
