Select the right potatoes: Choose quality potatoes that are suitable for frying, in fact they are high in starch and will provide a crispier texture in the balls.
Drain the potatoes well: After cooking the potatoes, be sure to drain them completely to remove excess water. This will help the balls keep their shape during frying.
Just the size of the balls: Try to keep a uniform size for the balls so that they cook evenly. Use a measuring spoon to make sure they are all the same size.
Control the temperature of the oil: Make sure the oil is hot but not too hot before adding the balls. Too much heat can cause the balls to brown too quickly on the outside and become raw on the inside.
Try different dressings: Experiment with different salad dressings. Try lemon or balsamic vinaigrettes, or add fresh herbs like cilantro or parsley for more flavor.
