Microwave macaroni cheese

Instructions

1. Step 1

   Put the pasta in a ceramic or glass microwavable bowl. Pour over 700ml boiling water and cook for 2 mins on high; stir and repeat twice more (6 mins in total). Drain the pasta and return it to the bowl.

2. Step 2

   Put the cornflour and 1 tbsp milk into a jug and stir to make a paste. Add the remaining milk and mix well. Pour over the pasta.

3. Step 3

   Mix in the mustard, along with the grated gruyère and cheddar, and stir well. You can cook the pasta in the same bowl or tip it into a microwavable serving dish.

4. Step 4

   Cook on high for 5 mins, stirring halfway through. Sprinkle over the parmesan and dot with small pieces of butter. Cook for a further 2 mins, then serve with a good grating of black pepper, if you like.
