This is a super easy recipe for a smooth and creamy béchamel sauce made in the Thermomix. It's a versatile base for various dishes, including lasagne, moussaka, gratins, and fish pie.

Béchamel sauce is simply butter and flour mixed together to make a roux. Then, milk and a pinch of nutmeg are added and heated until thickened. The key to success is continuously stirring the sauce so no lumps form.
Making it in the Thermomix saves time and effort. The machine's constant stirring and controlled heat ensure a creamy, lump-free sauce every time.

- Butter - use unsalted butter to control the salt content.
- Plain flour - use plain flour as self-raising flour, which contains baking powder which interacts with the other ingredients.
- Milk - use whole milk - lite milk results in a watery Béchamel.
- Nutmeg - optional - just a tiny pinch, as nutmeg is a strong spice.
