11: Pour the reduced stock into the pan (there should only be 5 or 6 tablespoonsful left) and use this to deglaze the bottom.
12: Add 250 ml cream and 3 pinches saffron. Turn down the heat and leave to reduce gently. When the saffron cream has reduced, checking the seasoning.

15: Stir gently and leave to heat through for a couple of minutes. Check the seasoning again before serving.
Remarks
If you do not have your own vegetable stock, use poultry stock or a stock cube and water. You can even just use salted water (in this case, do not reduce and replace the stock with a little white wine at stage 11).
