Notes
💡 Pro Tips for Extra Crispy Fritters
✔ Use sparkling water – It gives the batter an airy, crispy texture.
✔ Double fry – First to cook through, second to maximize crunch.
✔ Don’t overcrowd the pan – Fry in small batches to maintain oil temperature.
✔ Drain well – Use a paper towel or rack to prevent fogginess.
✔ Customize your dip – Try swapping sriracha for gochujang or sweet chili sauce.
