Footnotes
Cook's note:
Add a 1-inch cube of bread to the hot oil to check if it is ready. If it turns deep golden brown in color after a count of 40, the oil is ready. If the bread cube browns too quickly, turn down the heat and wait a few minutes for it to cool.
Editor's note:
We have determined the nutritional value of oil for frying based on a retention value of 10% after cooking. The exact amount will vary depending on cooking time and temperature, ingredient density, and the specific type of oil used.
