2. To make 10 portion:
 Calculate the ingredients you need for the number of portions according to your
group, in grams.
 First I calculate how much everything weighs .
 1,75 cups flour=> 1,75*250=435.5 grams flour
 A pinch of salt= about 4 grams of salt
 ¾ cup of butter=>3/4*250=187.5 grams of butter
 4-5 tablespoons of water=>4*250 or 5*250=1000-1250 grams of water=> average=1125
grams of water
 3 tablespoons unsweetened cocoa=>3*20=60 grams unsweetened cocoa

1 cup sugar=>250*1= 250 grams sugar
1 cup water=> 250*1= 250 grams water
2 tablespoons butter=>2*20= 40 grams butter
1/3 cup flour=> 1/3*250= 83 1/3 grams flour
3 egg yolk (1 egg yolk=19 grams)=>3*19= 57 grams egg yolk
2/3 cup milk=>2/3*250= 166 2/3 grams milk
1 teaspoon vanilla(1 teaspoon=5 grams)=>1*5= 5 grams vanilla

Then I make everything 1/10 bigger to make it for 11 portions.
435.5*1.1=479.05 grams flour
4*1.1=4.4grams of salt
187.5*1.1=206.25grams of butter
1125*1.1=1237.5grams of water
60*1.1=66 grams unsweetened cocoa
250*1.1=275grams sugar
250*1.1=275 grams water
40*1.1=44 grams butter
83 1/3*1.1= 91 2/3 grams flour
57*1.1=62.7grams egg yolk
166 2/3*1.1=183 1/3 grams milk
5*1.1=5.5 grams vanilla

4. To make 22 portions:
 Now double everything for 22 portions.
11 portions
22 portions

5. Flour - butter ratio
 958.1 grams flour + 183 1/3 grams flour= 1141,4333
grams flour
 412.5 grams of butter + 88 grams butter=500,5 grams
butter
 1141,4333/500,5= 2,28

Flour 1 kg= €0,94/22=€0.04
salt 1kg= €0,35/22=€0.02
Butter 500 gr.= €1,01/22=€0.05
(you don’t use water for a pie and you have a tap)
Cocoa 250 gr.= €2,99/22=€0.14
1kg sugar = €1,04/22=€0.05
(you don’t use water for a pie and you have a tap)
Butter 500 gr.= €1,01/22=€0.05
Flour 500g = € 0,52/22=€0.02
Egg yolk (6 eggs) = € 1,09/22=€0.05
Milk 0,5L =€ 0,54/22=€0.02
Vanille 1,5g = € 1,25 => 8*1,25= €10/22=€ 0.45
So, per piece: €0.89

8. Baking temperatures
 The pie is to be baked for 15 minutes at 210 degrees C, then for 40-45
minutes at 180 degrees C.
 the formula: F=9/5*C+32
 F=9/5*210+32 => F= 410 degrees Farenheit for 15 min.
 F=9/5*180+32 => F= 356 degrees Farenheit for 40-45 min.
