All-purpose flour is generally the best choice for making samosas due to its balance of gluten content, which provides the necessary structure and flakiness.
All-purpose flour strikes a good balance between gluten development and tenderness, making it ideal for samosa dough. Gluten is what gives the dough its elasticity and strength, allowing it to be rolled out thinly and hold its shape during frying. Too much gluten, and the samosa will be tough; too little, and it will be crumbly and difficult to work with.
While some recipes may incorporate a small amount of other flours like whole wheat flour for added flavor or semolina for extra crispness, all-purpose flour forms the base for a reliable and delicious samosa crust. The key is to not overwork the dough, which can develop too much gluten and result in a tough samosa.
The fat content in the dough (usually ghee or oil) also plays a crucial role in creating a flaky texture. The fat coats the flour particles, preventing them from forming long gluten strands. This results in a more tender and flaky crust.
Rest the samosa dough for at least 30 minutes (or even longer) after kneading. This allows the gluten to relax, making the dough easier to roll out and preventing it from shrinking back during shaping.
