I make my own shortcrust but for today I let you of if you buy some.
Pastry
250 gr plain flour
1 flat tsp of salt
125 gr of butter or margarine
Water
all in one bowl, rub fat in flour until it feels sandy, add a bit of water slowly, until you reach dough consistency
preheat the oven to 240 degrees centigrade
filling for cheese ones
I do not really have measures for that because I usually just play it by ear:
grate some cheddar cheese
Make a "liason2 with one egg, abit of milk, salt pepper and ground nutmg to taste.
Method
roll dough to about 1 or 2 mm cut round shapes with biscuit cutter ( a glass works as well if you don't have cutters)
grease a muffin tin and flour it, put the cut pastry in add some of the grated cheese and a teaspoon of the liaison (usually enough but you will see) do not fill too much as the filling tends to swell when in the oven)
cook in oven until smelling lovely and looks golden brown.
for the spinach ones I make a bechamel (I think it is the equivalent of white sauce)
a bit of oil in a pan, let heat, add about 1 heaped tbsp of flour,
when flour and oil are "blending, add some milk, depending on what qtty you want carry on mixin it all until the milk thickens. At that stage I add chopped frozen spinach and leave on a low heat stove until spinach defrost. When the mixture looks ready, add some grated cheese, salt pepper, nutmeg to tast and procede ad before with the dough.
you do not need a liaison for the spinach one.
I am really sorry not to be able to give more precise measurements but I hardly ever weigh nything.
