Filling :
250g Frankfurters, cut in thin slices.
200g (500ml) grated cheese
40g (50ml) butter/margarine
1 onion, chopped
1 spoon Worcester sauce
1 spoon mustard
2 spoons Mrs Balls chutney (South African brand! but optional)
1 egg yolk, mixed with 25ml milk
fresh coriander and rosemary

Pastry :
275g (500ml) flower
20 ml baking powder
2 ml salt
125g butter/margarine
150ml milk

Preheat oven to 200°C (400°F).
Mix flower, baking powder & salt.
Mix butter thoroughly into the flower mixture with fingers.
Add milk in a slow stream and mix; a fairly firm dough should be the result.
Roll out the dough on a flower-covered surface in a 35x27 cm square.
Fry the onion in a bit of oil till soft.
Add the frankfurters & fry for a few minutes.
Mix the cheese, Worcester sauce, chutney, mustard & coriander in a big bowl.
Add the fried frankfurter & onion to that & mix.
Cover the pastry evenly with the mixture.
Roll the pastry like a Swiss Roll and place on a baking tray.
Cut the roll in slice 1.5-2cm thick, but don\'t cut all the way through; the bottom should stay in one piece.
Paint with egg yolk mixture.
Bake for 20 minutes or till golden brown
Garnish with fresh rosemary & serve hot.
