Curried Tripe

Ingredients

Directions

Blanch the tripe by boiling it in cold water, then remove it immediately.
Cut the tripe into small pieces.
Place the tripe pieces in a saucepan and cover with cold water.
Peel the onion and cut it partially through, then add it to the saucepan.
Bring the saucepan to a boil, then reduce to a simmer for 2.5 hours.
Check the tripe for tenderness with a fork.
Remove the saucepan from the heat and place it on a paper on the table.
Use a fork to transfer the tripe pieces to a dish.
In a small saucepan, combine the flour, curry powder, and dripping, mixing well with a wooden spoon.
Add enough cold water to form a stiff paste.
Pour in ½ pint of the tripe cooking liquid.
Heat the mixture, stirring until it boils and thickens without lumps.
Stir in the brown sugar and salt to taste.
