Peel the prawns, leaving the tails intact. Gently
pull out the dark vein from each prawn back,
starting at the head end. Cover and set aside.
Heat the oil in a large saucepan, add the bacon and
cook over a medium heat for 5 minutes. Stir in the
flour and cook, stirring, until the flour turns
nutty brown. Remove from the saucepan. This mixture
will be used to thicken and flavor the gumbo.
Heat the extra oil in the saucepan, add the onion,
cayenne and peppers and cook, stirring, over a
medium heat for 5 minutes, or until the onion is
golden brown.
Add the okra, bay leaf and tomatoes
to the saucepan and bring to the boil.
Reduce the
heat and simmer for 30 minutes. You may need to add
water if the mixture is too thick.
Stir the prawns
and the roux into the mixture and season to taste
with salt and pepper and Tabasco sauce. Cook for 5
minutes, or until the prawns are cooked.
