Instructions:
- Peel and grate or thinly slice the onions. If grating, gently squeeze out excess moisture using a clean tea towel.
- In a large mixing bowl, whisk together the flour, baking powder, salt, pepper, and sugar.
- In a separate small bowl, whisk the eggs and milk until just combined.
- Pour the wet mixture into the dry mixture. Whisk briefly until just incorporated. A few lumps are perfectly fine; do not overwork the batter.
- Gently fold the prepared onions into the batter until evenly distributed. Let the batter rest for 10 minutes.
- Pour the oil into your skillet to a depth of about ½ inch. Heat over medium-high heat until the oil shimmers (approximately 350°F / 175°C).
- Drop large tablespoons of the batter into the hot oil, spacing them well apart to avoid overcrowding the pan.
- Fry for 3–4 minutes per side until deeply golden brown and cooked through.
- Carefully remove the fritters with a slotted spoon and place them on paper towels or a wire rack to drain excess oil. Season immediately with an extra pinch of salt while hot.
- Serve hot, optionally with sour cream and chives or apple butter.
