A Snack Steeped in Tradition
For many, banana chips, or 'ethakka upperi', are more than just a snack; they are a taste of home. Traditionally associated with Kerala, these golden discs are a staple during festivals like Onam and a perfect accompaniment to a cup of chai. The authentic
flavour comes from a few key elements: thinly sliced raw bananas, specifically the starchy Nendran variety, fried to perfection in coconut oil, and seasoned with turmeric and salt. This deep-frying method is what creates the legendary crunch. However, it also means the chips absorb a significant amount of oil, a concern for the health-conscious snacker.
The Air Fryer: A Healthier Path to Crunch
Enter the air fryer, a kitchen appliance that has revolutionised how we cook. It works by circulating superheated air at high speed, creating a crispy exterior on food with minimal oil. This method drastically cuts down on fat and calories compared to traditional deep-frying. While deep-frying submerges food in hot oil, air frying requires just a light toss or spray, often using 70-80% less oil. This makes it possible to recreate your favourite crunchy snacks, like banana chips, without the guilt and excess grease associated with deep-frying.
The Method for Perfect Air-Fried Chips
Making crispy, flavourful banana chips in an air fryer is surprisingly simple. The key is using the right bananas and preparing them correctly. Start with two to three firm, raw green bananas; Nendran are traditional, but any starchy cooking plantain will work well. Peel the bananas and slice them into very thin, uniform rounds, about 1/8th of an inch thick. A mandoline slicer is ideal for consistency. Immediately soak the slices in a bowl of cold water with a teaspoon of turmeric powder and a pinch of salt for about 10 minutes. This prevents browning and infuses the chips with their characteristic colour. Next, drain the banana slices thoroughly and pat them completely dry with a clean cloth or paper towels. This step is crucial for achieving maximum crispiness. Toss the dry slices in a bowl with just half a teaspoon of coconut oil until they are lightly coated. Preheat your air fryer to 180°C. Arrange the banana slices in a single, even layer in the air fryer basket, ensuring they don't overlap. You will likely need to cook in batches. Air fry for 10-15 minutes, shaking the basket or flipping the chips halfway through, until they are golden brown and crisp. The exact time will vary based on your air fryer and the thickness of your slices.
Tips for an Authentic Taste
To elevate your air-fried chips from good to great, a few pro tips can help you capture that authentic regional flavour. First, do not skip the turmeric soak; it is essential for the classic colour and taste. While any neutral oil works, using a small amount of coconut oil will impart a more traditional aroma and flavour. Ensure your banana slices are as thin and uniform as possible. Thicker slices will have a softer, chewier texture rather than a definitive crunch. Finally, allow the chips to cool completely on a wire rack after removing them from the air fryer. They will continue to crisp up as they cool down to room temperature. Once cool, store them in an airtight container to maintain their crunch.
