Ensure your fritter batter is cold, use a high-quality oil at the correct temperature (around 350-375°F or 175-190°C), and don't overcrowd the pan.
Preventing fritter batter from absorbing too much oil involves several key factors working together. First, the temperature of the batter is crucial. Cold batter helps to create a quicker temperature differential when it hits the hot oil, causing the outside to cook and seal faster, thus minimizing oil absorption. You can achieve this by chilling the batter in the refrigerator for at least 30 minutes before frying.
Second, the oil temperature is equally important. If the oil isn't hot enough, the batter will sit and soak up the oil instead of cooking quickly. Aim for an oil temperature between 350-375°F (175-190°C). Use a deep-fry thermometer to monitor the temperature accurately. Using a high-quality oil with a high smoke point, such as peanut, canola, or vegetable oil, is also recommended. These oils can withstand the high temperatures needed for frying without breaking down and imparting off-flavors.
Finally, avoid overcrowding the pan. Adding too many fritters at once will lower the oil temperature, leading to increased oil absorption. Fry in batches, ensuring there's enough space around each fritter for even cooking.
Adding a small amount of alcohol, like vodka or gin (about a tablespoon per cup of batter), can help reduce oil absorption. The alcohol evaporates quickly during frying, creating tiny air pockets that prevent the oil from penetrating the batter.
