  1. Definitely nicer with thin cream (pure cream), and at least 400ml added at beginning and possibly more when you add the spinach and cheese if it looks like it needs it. I added an extra 200ml at the end stage this time.

  2. This was delicious! All of my young children loved it. I used long life light cooking cream and it was delish! Definitely going on the regular list!

  3. 5 stars
    I used chicken soup instead of asparagus and pasta instead of rice. The pasta went in for the last hour. Loved it and it made a tonne.
