Filling ratio: for less sweetness, use up to 2/3 cup coconut to 1/2 cup sugar.
Dates, nuts, and raisins bulk up the filling: chop small, do not overfill cones, and reduce sugar slightly if you use the full optional set.
Egg option: some traditional recipes add one beaten egg to the coconut mixture for binding. If you use egg, reduce or omit milk.
Best within an hour of frying; sugar in the dough and filling makes them firm as they cool. Store same day at room temperature in a loose container; re-crisp in an oven or air fryer if needed.
Puff pastry shortcut: small squares of store-bought puff can be filled and baked or air-fried; flavor and texture differ from wheat dough.
Freeze shaped uncooked samosas on a tray, then bag; fry from frozen on medium heat until deeply golden (expect slightly more oil absorption).
