Prepare Dough: Mix all-purpose flour with salt and a little oil. Add water gradually and knead into a stiff dough. Let it rest for 20–30 minutes.
Prepare Filling: Take leftover spiced rice in a bowl. If needed, lightly mash or mix to combine grains evenly. Add extra spices or herbs for enhanced flavor.
Shape Samosas: Divide dough into small balls, roll into oval shapes, cut in half, form cones, and fill with rice mixture. Seal edges with water.
Frying: Heat oil on medium flame and deep fry until golden brown and crispy.
Serve: Serve hot with ketchup, chutney, or curd dip.
