2. How do I achieve thin and crispy onion straws?
To achieve thin and crispy onion straws, it’s important to slice the onions very thinly. You can use a mandoline slicer or a sharp knife to get thin, uniform slices. Thinner slices tend to crisp up better during frying.

Yes, you can make crispy onion straws without a deep fryer. Simply heat oil in a deep skillet or pot until it reaches a temperature of around 350°F (175°C). You can use a candy or deep-fry thermometer to monitor the temperature. Fry the onion straws in batches, ensuring they have enough space to cook evenly.

4. What type of oil is best for frying crispy onion straws?
Vegetable oil or canola oil is commonly used for frying crispy onion straws due to their high smoke point and neutral flavor. These oils work well for achieving a crispy texture. However, you can also use other oils with a high smoke point, such as peanut oil or sunflower oil.
