All-purpose flour is generally considered the best flour for making samosas due to its balance of gluten content, which provides the necessary structure and flakiness.
The ideal flour for samosas should create a dough that is sturdy enough to hold the filling without tearing, yet also tender and flaky when fried or baked. All-purpose flour strikes this balance effectively. Here's why:
Gluten Content: All-purpose flour has a moderate gluten content. Gluten is the protein that develops when flour is mixed with water, providing elasticity and structure to the dough. Too much gluten can result in a tough samosa crust, while too little can make it crumbly and difficult to work with.
Texture: The moderate gluten content of all-purpose flour allows for a dough that can be rolled out thinly without tearing, resulting in a flaky and crispy crust when cooked.
Availability: All-purpose flour is widely available and relatively inexpensive, making it a convenient choice for most home cooks.
Alternatives: While all-purpose flour is the standard, some recipes may incorporate a small amount of semolina (sooji) or gram flour (besan) to add extra crispness or a slightly nutty flavor. However, these should be used sparingly and in combination with all-purpose flour.
For an extra flaky crust, try adding a tablespoon or two of ghee (clarified butter) or oil to the flour before adding water. This helps to shorten the gluten strands, resulting in a more tender and flaky texture.
