Batter Fried Fish with Cheese Sauce

INGREDIENTS
8 (750 gm) fish fillets
1 Tbsp lemon juice
1 tsp salt
2 Tbsp all purpose flour for dusting
Oil for deep-frying
Chopped greens for garnish
For the batter
1/2 cup (60 gm) all purpose flour
1 Tbsp (15 gm) oil
1/2 cup water
1 egg, white only
1 tsp salt or to taste
For the sauce
2 cups (480 gm) milk
2 Tbsp (15 gm) all purpose flour
1 Tbsp oil
1 tsp salt or to taste
1/4 tsp powdered black pepper
1 cup (120 gm) cheese, grated

METHOD
Marinate fish, lemon juice and salt for 5 minutes and wash off.
From the batter ingredients, mix together the flour, salt and oil. Add the water gradually, mix into a batter and keep aside.
Heat oil and add flour. Saute till flour emanates an aroma. Take pan off the fire and add milk, stirring vigorously all the time to avoid lumps. Put pan back over heat and bring to a boil, stirring continuously. Season with salt and pepper and add the cheese to mix well. Take off the heat and keep aside.
Wash and wipe the fish dry. Dust lightly with flour, patting off any excess flour.
Heat oil for frying, and while it is heating, whip egg-white stiff and fold into the batter.
When oil is ready, dip the fish into the batter, shake off the excess and fry to a very light golden on both sides. Place it on an absorbent paper to drain off the excess fat.
Immediately before serving, fry the fish once again in hot oil, drain and arrange in a serving dish. Pour some of the hot cheese sauce over it (serving the rest of it on the side) and garnish with the greens.
