Double deep frying is a cooking technique that has gained popularity worldwide for its ability to produce crispy, golden-brown foods with a tender interior. This method involves frying food not once, but twice, with a resting period in between. The result is a texture and flavor that is hard to achieve with traditional frying methods. In this article, we will delve into the world of double deep frying, exploring its history, benefits, and most importantly, how to do it correctly.
Introduction to Double Deep Frying
Double deep frying, also known as double frying, is a technique that originated in Asian cuisine, particularly in Korea and China. It was initially used to cook potatoes and other root vegetables but has since been applied to a wide range of foods, including meats, seafood, and even desserts. The principle behind double deep frying is to first fry the food at a lower temperature to cook it through, then let it rest before frying it again at a higher temperature to crisp the exterior.
The Science Behind Double Deep Frying
The science behind double deep frying lies in the way it affects the starches and moisture content of the food. When food is fried at a high temperature, the outside cooks quickly, but the inside may remain undercooked. By frying the food at a lower temperature first, the heat penetrates more evenly, cooking the food through without burning the outside. The resting period allows the food to cool slightly, which helps to redistribute the moisture and starches. When the food is fried again at a higher temperature, the outside becomes crispy, while the inside remains tender.
Benefits of Double Deep Frying
There are several benefits to using the double deep frying method. Improved texture is one of the most significant advantages, as it allows for a crispy exterior and a tender interior. Double deep frying also helps to reduce oil absorption, making the food less greasy. Additionally, this method can enhance flavor, as the initial frying can help to seal in seasonings, and the second frying can add a caramelized flavor to the food.
How to Double Deep Fry
Double deep frying may seem like a complicated process, but it is relatively straightforward once you understand the basic steps. Here is a general guide on how to double deep fry:
To start, you will need a deep frying vessel, such as a deep fryer or a large pot with at least 3-4 inches of oil. The type of oil used is crucial, as it needs to have a high smoke point to withstand the high temperatures. Peanut oil, avocado oil, and grapeseed oil are good options.
First, heat the oil to the initial frying temperature, which is usually around 325°F (165°C). Prepare your food by cutting it into the desired shape and size. If necessary, dust the food with a light coating of starch, such as cornstarch or flour, to help it fry more evenly.
Carefully place the food into the hot oil in batches, if necessary, to avoid overcrowding the pot. Fry the food for the recommended time, usually 3-5 minutes, or until it is cooked through but not yet crispy. Remove the food from the oil with a slotted spoon and place it on a paper towel-lined plate to drain excess oil.
Let the food rest for at least 30 minutes to allow the moisture to redistribute. This step is crucial, as it will affect the final texture of the food. During this time, you can increase the oil temperature to around 375°F (190°C) for the second frying.
Once the food has rested, carefully place it back into the hot oil in batches. Fry the food for an additional 2-3 minutes, or until it reaches the desired level of crispiness. Remove the food from the oil and place it on a paper towel-lined plate to drain excess oil.
Tips for Successful Double Deep Frying
To achieve the best results with double deep frying, follow these tips:
- Use the right type of oil with a high smoke point to prevent it from burning or smoking during the frying process.

What is double deep frying and how does it differ from regular deep frying?
Double deep frying is a cooking technique that involves frying food twice, with a resting period in between, to achieve a crispy exterior and a tender interior. This method is different from regular deep frying, where food is fried only once, as it allows for better control over the cooking process and results in a more desirable texture. The first fry, typically done at a lower temperature, helps to cook the food partially and remove excess moisture, while the second fry, done at a higher temperature, crisps up the exterior.
The key to successful double deep frying lies in the resting period between the two fries, which can range from a few minutes to several hours, depending on the type of food being cooked. During this time, the food is allowed to cool and dry out slightly, which helps to prevent it from becoming greasy or soggy when it is fried again. By controlling the temperature and timing of the two fries, as well as the resting period, cooks can achieve a level of crispiness and texture that is difficult to attain with regular deep frying. This technique is particularly useful for cooking foods like french fries, chicken, and doughnuts, which require a delicate balance of crunch and tenderness.
What are the benefits of using double deep frying in cooking?
The benefits of using double deep frying in cooking are numerous.
