Creating battered sausages is a straightforward process if you follow these steps:

1. Prepare the Sausages: Start by removing the sausages from their packaging. You can prick them a few times with a fork to prevent bursting while cooking.

2. Make the Batter: In a mixing bowl, combine the flour, baking powder, salt, and black pepper. Gradually pour in the cold sparkling water while whisking to form a smooth batter.

3. Heat the Oil: In a deep frying pan or pot, heat vegetable oil over medium heat. You’ll need enough oil to submerge the sausages completely, about 2-3 inches deep.

4. Coat the Sausages: Once the oil is hot, dip each sausage into the batter, ensuring they’re fully coated. Allow any excess batter to drip off before frying.

5. Fry the Sausages: Carefully place the battered sausages into the hot oil, being cautious of splattering. Fry in batches for about 5-7 minutes or until golden brown and crispy. Use a slotted spoon to remove them and drain on paper towels.

6. Cool and Serve: Let the battered sausages cool for a minute before serving.
