Spinach, mozarella, milk, double cream
There are many different ways to make spinach dip - this method is one that I use when I'm serving spinach dip cold and don't want it to congeal or solidify into solid cheese.
1) layer a handful of spinach and a handful of grated mozarella in a microwaveable bowl and add a teaspoon of double cream. Heat for 30 seconds and then stir vigorously with a spoon. Add more spinach and another teaspoon of cream and heat for another 30 seconds.
2) Continue stirring vigorously and add the milk in a steady trickle until the mozarella has ceased to be elastic and has begun to absorb the milk.
3) Add more spinach for liquid and heat for a final 30 seconds.
Perfect served with bread or nachos
