Sambusa and samosa are both savory pastries filled with spiced vegetables or meats, but they have slight differences in shape, ingredients, and regional origins. Sambusa is a triangular-shaped pastry with a thinner and crispy shell that is popular in East Africa and the Arabian Peninsula. It is traditionally filled with beans, lentils, or meat, and flavored with spices like cumin, coriander, and curry powder. Samosa, on the other hand, is a pyramid or cone-shaped pastry with a thicker and flakier shell that is more popular in South Asian cuisine. It is typically filled with spiced potatoes or peas, but can also contain meat, paneer, or cheese. Both sambusa and samosa are often served as a snack or appetizer, either fried or baked.
