For the pastry
Preheat oven to 200C/400F. If you have a food processor, add flour, salt and butter and process until you have a fine crumb. Alternatively add to a large bowl and rub the mixture between your fingers to break up the butter into small pieces. You should still have small pieces of butter throughout the mixture.
Add eggs, milk. Process until a ball forms. If using your hands, miss with a wooden spoon then knead with your hands until incorporated. Roll out dough between sheets of baking paper. Place in the fridge until firm. About 15 minutes.
Grease tart tin with softened butter and line with pastry. I used a 30cm tart tin with a depth of 4cm. Line with baking paper and fill with weights. Bake for 15 minutes, remove weights and cook for a further 10 minutes or until lightly golden. Set aside. Lower heat to 180C/350F.
