thaw the frozen spinach, then squeeze dry, chop and set aside.
place smoked haddock in a pan and cover with milk; bring to the boil and simmer for 3-4 minutes, until the fish is just cooked; drain, discarding the milk, and set aside.
pre-heat oven to 190°C static.
in a large pyrex mixing bowl or similar, mix together eggs, ricotta, cream, Parmesan, minced garlic, cayenne pepper, white pepper and salt.
roughly flake the fish and fold it gently into the ricotta mix with the chopped spinach.
fill the pastry case with the mixture and bake for 30-35 minutes, until golden and firm to the touch.
allow to cool a little before slicing.
