Step-by-step instructions

1. 1

   Place the onion in a large bowl, cover it with buttermilk and seal with plastic wrap. Let it soak at room temperature for 30 minutes to 1 hour.

2. 2

   Spread 100 g of all‑purpose flour on a large plate and mix with cayenne pepper and a small amount of seasoning. Drain the onion rings, then coat them in the seasoned flour.

3. 3

   Fill a large pot with oil up to half and heat until the temperature reaches 180 °C, using a thermometer (or until a piece of bread browns in 20–30 seconds). Alternatively, preheat the deep‑fryer to 180 °C. Prepare the batter by mixing the remaining all‑purpose flour with corn starch and a pinch of salt. Make a well in the centre and pour in the beer. Stir until the mixture is smooth.

4. 4

   Dip each onion ring into the batter and fry for 3–4 minutes until crispy. Drain on a paper towel and sprinkle with the coarse sea salt crystals.
