What type of starch is in lasagne cheese sauce?

Here's why:

* Thickening Agent: Flour is a key ingredient in béchamel sauce, the foundation for many cheese sauces, including those used in lasagne. It creates the creamy, thick consistency we associate with lasagne sauce.

* Gluten Development: Wheat flour contains gluten, which forms a network that traps moisture and creates a smooth, velvety texture.

However, other starches can be used, though they are less common:

* Cornstarch: A gluten-free option that can be used as a substitute for flour. It's often preferred for its ability to create a clear, glossy sauce.

* Potato Starch: Another gluten-free option that can be used as a substitute for flour. It provides a slightly different texture compared to wheat flour.

Ultimately, the type of starch used in lasagne cheese sauce will depend on the specific recipe and the desired texture.
