Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Preheat the oven to 400°F (200°C).
Roll out the puff pastry and cut into circles.
Place the circles on a baking sheet and bake until golden brown.
In a pan, melt butter and add diced chicken and shrimp.
Stir in mushroom ketchup, Worcestershire sauce, lemon peel, and curry powder.
Season with coarse sea salt and black pepper.
Add cream to the mixture and heat through.
Fill the baked pastry shells with the mixture and serve.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
