Now I don’t have to wonder if less oil for deep frying is better than more oil. This evening while deep frying some potatoes to go with burgers, I opted to use just enough oil to just cover the frozen potatoes. Once the oil was at 375, I added the potatoes to the hot oil and watched as the temperature really plunged. Then it dawned on me that more oil is better since more oil holds more heat.
After that batch finished, I added about twice as much oil as was already in there, returned the oil to 375 and fried the same amount. Sure enough the oil temperature dipped but not nearly as much.
So, what have we learned today? More oil, at least twice as deep at the items being fried, is better for deep frying.
