Cook the noodles in a large pan of salted boiling water per the packet instructions. Drain and reserve 100 ml of the pasta water.

Melt the butter gently in a pan large enough to hold all the pasta. Add the lightly crushed poppy seeds and simmer for 1 minute, then add the pasta and stir well. Add a little pasta water if the pasta/ butter mixture is a little dry.

Sprinkle the icing sugar evenly over the pasta and stir well. Taste and add more sugar if you prefer it a little sweeter.
