Deep Frying Tips
- Food pieces should be uniform in size so they will cook evenly.
- Pat food to dry it before battering or breading.
- Lower food into hot oil slowly to prevent splattering.
- Fry food in several small batches to prevent the oil temperature from dropping.
- Pieces of food should not be touching each other, or they could cook unevenly.
- Remove food with a metal slotted spoon or strainer to paper towels or a rack. To keep batches warm, place the food in a pan lined with paper towels and keep it warm in a preheated 200 F oven.
- Remove small particles of food left behind. If they are left in the oil and burn, they could cause discoloration and shorten the life of the oil.
- If you are using an electric deep fryer with a plastic lid, make sure the oil has cooled before you replace the lid.
Reusing and Filtering Cooking Oil
Cooking oil eventually breaks down after repetitive exposure to high heat, water, and food particles. If the oil begins to smoke at normal deep-fry temperatures, appears discolored, smells rancid or stale, or foams around the frying food, it's probably time to replace the oil.
If you filter the oil and store it properly, it should be good for dozen or more uses.
Filter used oil through a specially made paper filter made for cooking oils, or use a fine mesh strainer to catch food particles. Pour the oil through the filter paper or strainer into a storage container. Cover and refrigerate the oil or store it in a cool place.
Oil used for frying fish could impart a fishy flavor to other items, so keep oil used for frying fish in a separate container and only use it for frying fish.
