One of the first things I learned to cook on the hob was white sauce and this recipe uses the method I was taught.
Method
- Firstly make the slime…put approx. one cup of cornflour in a bowl
- Add half a cup of water and a few drops of food colour
- Carefully stir it and add a little more water to make the slime the desired consistency
- Whilst that entertains the kids, boil a kettle and cook the pasta according to the pack instruction
- Meanwhile, melt 40g of butter in a saucepan then remove from the heat
- With a wooden spoon, stir in around 25g cornflour and cook, stirring, for one minute
- Off the heat, gradually add 450mL milk, stirring to mix well (you can also use a whisk)
- Back on the heat, stirring all the time, cook until you feel it thicken and it coats the back of the spoon
- Add salt, pepper, nutmeg and grated cheese to taste and set aside
- Just before the pasta cooking time is up, add a handful of peas to the pasta water
- Drain the pasta and peas, add the white sauce and serve topped with more cheese if liked
Science in a Sentence
The mixture flows like a liquid but when you squeeze it feels like a solid; this is called a non-Newtonian fluid. You can find out more here.
Notes
