- 250 g
(9oz) frozen spinach, thawed
- 4
large eggs, separated
Fresh nutmeg, grated
3½ tbsp cornflour
- 15 g
(½oz) butter
- 2
shallots, finely sliced
- 350 g
(12oz) mushrooms, sliced
- 400 ml
(14fl oz) skimmed milk
- 25 g
(1oz) vegetarian mature Cheddar, grated
- 1 tsp.
English mustard
- Step 1
Preheat oven to 190°C (170°C fan) mark 5. Line a 30.5cm x 23cm (12in x 9in) tin with baking parchment. Squeeze out as much moisture as you can from the thawed spinach and put into a large bowl. Stir in egg yolks, nutmeg and plenty of seasoning.
- Step 2
Put egg whites into a separate bowl and whisk until they hold stiff peaks. Quickly beat in 1½tbsp of the cornflour, then fold the mixture into the spinach bowl. Empty on to the prepared tin, spreading it to the corners, then cook for 12-15min until golden and firm to the touch.
- Step 3
Meanwhile, heat butter in a large frying pan and cook shallots for 5min until softened. Turn up the heat and add the mushrooms. Cook for 8-10min until softened and any water in the pan has evaporated. Stir in remaining cornflour, then the milk. Heat, stirring, until thickened. Stir in cheese and mustard and check the seasoning.
- Step 4
Take spinach base out of the oven and transfer with the paper to a board. Slide a palette knife underneath the roulade to loosen, if necessary, then spread the mushroom mixture over the top. Roll up lengthways as neatly as you can (don't worry if there's some spillage) and serve warm in slices with a green salad.
