For crispier pancakes, make sure to squeeze out as much moisture as possible from the potatoes and onions.
Use a non-stick or well-seasoned cast-iron skillet to prevent sticking.
You can also add finely chopped herbs like chives or parsley to the batter for extra flavor.
To keep pancakes warm while cooking in batches, place them on a baking sheet in a low oven (around 200°F or 95°C).
