Assemble all your ingredients so everything is ready before you start mixing.
Prepare the corn: If using fresh corn, strip the kernels from the cob. If using frozen corn, thaw completely. Drain the kernels very well, then squeeze handfuls firmly to remove as much moisture as possible—excess liquid will make the mixture too loose to fry.
Process the corn: Place most of the drained kernels into a food processor and blend until mostly smooth. Leave a handful of kernels unblended for texture.
Beat the egg and set it aside.
Prepare the aromatics: Finely chop the shallot or red onion. Finely chop the coriander (root, stems, and leaves). Finely dice the long red chilli.
Mix the flavour base :In a mixing bowl, combine the processed corn, the reserved whole kernels, coriander, shallot/onion, and long red chilli. Add the red curry paste and mix well.
Add the binding ingredients: Add the beaten egg, then sprinkle in the rice flour. Mix until a cohesive batter forms.
Heat the oil: Pour vegetable oil into a frying pan and heat over medium heat until shimmering.
Portion directly into the pan: Using an ice cream scoop or large spoon, scoop the mixture straight from the bowl into the hot oil. This batter is soft, so placing it directly into the pan helps it hold its shape. Gently flatten each fritter with the back of the spoon.
Fry until golden: Cook the fritters until golden brown on the first side, then flip and fry the other side until crisp and golden.
Keep warm: Transfer cooked fritters to a tray and keep warm in a low oven while you finish frying.
Storage: Store leftovers in the fridge for up to five days. Reheat in the oven until hot and crisp.
