Begin by whisking together 3 large eggs, 2 tablespoons cornstarch, 2 tablespoons water, ½ teaspoon salt, and ¼ teaspoon ground black pepper in a bowl until the mixture is completely smooth. Set this aside.
Thinly slice 2 cups of fresh okra at an angle. Chop 2 stalks of spring onions, keeping the white and green parts separate. Mince 3 cloves of garlic.
Heat 2 tablespoons of oil in a non-stick pan over medium heat (350°F/175°C). Add the minced garlic and white parts of spring onions, cooking until fragrant, about 1 minute. Add the sliced okra and stir-fry for 2 minutes. Remove the vegetables from the pan and let them cool slightly.
Once cooled, gently mix the cooked vegetables into your egg mixture. Add the green parts of spring onions and stir to combine everything evenly.
Heat 3 tablespoons of fresh oil in your pan over medium-low heat (325°F/165°C). To test if the oil is ready, drop a tiny bit of egg mixture in - it should sizzle gently. For each piece, scoop about ⅔ cup of the mixture into the hot pan. Use your spatula to gently flatten and shape it into a round patty.
Cook each piece for 3 minutes on the first side, or until golden brown. You'll know it's ready to flip when the edges start to look set. Carefully flip and cook for another 3 minutes on the other side.
Serve immediately while hot and crispy. Pair with banana ketchup or spiced vinegar (suka) for dipping. Each batch of mixture should make 4-6 pieces, depending on your preferred size.
Note: If cooking multiple pieces, wipe the pan clean with paper towels and add fresh oil between batches to prevent burning and ensure even browning.
