Cauliflower with cream sauce
 

The way I make mine is that I add the sauce to the cauliflower right before serving.

I just mix 1/4 to 1/2 cup heavy cream and one egg yolk and 1/4 cup or more shredded Gruyere.

If it is too thick add some water if too thin add more cheese.

Cook sauce until thickened stirring constantly.

I make it for one serving or two.

I forgot to mention that you should cook the yolk with the liquid before adding the cheese.
Enjoy.
