Recipe Notes
Always fry a single piece to check if its crispy. If it turns out very hard to bite, it means the dough needs more butter. If it breaks easily, then add more flour.
Make this snack in batches. Keep the dough covered with a wet cloth.
Make sure to check if oil is ready. You can check by dropping a small ball of the dough in the hot oil and if it immediately comes on top, oil is ready.
