2. A collaborative task in the ComeniuseTwinning project “AIMS- Alternatives
for Innovative Math Study”

3. First, we went to the shop… There were so many
products, we could not decide what to buy!

4. Finally, we chose the things we needed and bought
them.

6. The ingredients we need for one pie (10 portions), in grams (1 cup = 250
g; 1 tablespoon = 20 g):
For the dough:
* flour - 1.75 cups = 1.75 x 250 g = 437.5 g = approx. 440 g
* salt - a pinch = half of a tablespoon = 20 g : 2 = 10 g
* butter (cut into small pieces) - 3/4 cup = 3/4 x 250 g = 187.5 g =
approx. 190 g
* cold water – 4.5 tablespoons = 4.5 x 20 g = 90 g (= 90 ml)
For the filling:
* unsweetened cocoa - 3 tablespoons = 3 x 20 g = 60 g
* sugar - 1 cup = 1 x 250 g = 250 g
* water - 1 cup = 1 x 250 g = 250 g (= 250 ml)
* butter - 2 tablespoons = 2 x 20 g = 40 g
* flour - 1/3 cup = 1/3 x 250 g = 83.(3) g = approx. 80 g
* 3 egg yolks
* milk - 2/3 cup = 2/3 x 250 g = 166.(6) g = approx. 170 g (=approx. 170
ml)
* vanilla - 1 teaspoon = 1 x 20 g = 20 g (= approx. 20 ml)
(we use a total of 440 g + 80 g = 520 g of flour and a total of 190 g + 40 g
= 230 g of butter)

7. Price of a pie (10 portions):
520 g flour costs: 520 g / 1000 g x 3.50 lei = 1.82 lei
10 g salt costs: 10 g / 1000 g x 1.70 lei = 0.017 lei
230 g butter costs: 230 g/250 g x 7.99 lei=7.3508 lei
90 ml of cold water costs: 90 ml/500 ml x 2.59 lei = 0.4662
lei
60 g of unsweetened cocoa costs: 60 g/100 g x 3.00 lei =1.8
lei
250 g sugar costs: 250 g/1000 g x4.29 lei=1.0725 lei
250 ml of water costs: 250 ml / 500 ml x 2.59 lei = 1.295 lei
170 ml milk costs: 170 ml/1000 ml x 5.49 lei = 0.9(3) lei =
approx 0.93 lei
20 ml vanilla costs: 20 ml/20 ml x 2.60 lei = 2.60 lei
TOTAL: 1.82 lei + 0.017 lei + 7.3508 lei + 0.4662 lei + 1.8 lei +
1.0725 lei + 1.295 lei + 0.93 lei + 2.60 lei = 17.3515 lei

8. Ingredients needed for one portion of pie:
flour: 520 g / 10 = 52 g
salt: 10 g / 10 = 1 g
butter: 230 g / 10 = 23 g
cold water: 90 ml / 10 = 9 ml = 9 g
unsweetened cocoa: 60 g / 10 = 6 g
sugar: 250 g / 10 = 25 g
water: 250 ml / 10 = 25 ml = 25 g
milk: 170 ml / 10 = 17 ml = approx. 17 g
vanilla: 20 ml / 10 = 2 ml = approx. 2 g

9. Price for one portion of pie:
o 52 g flour costs: 52 g / 1000 g x 3.50 lei = 0.182 lei
o1 g salt costs: 1 g / 1000 g x 1.70 lei = 0.0017 lei
o23 g butter costs: 23 g / 250 g x 7.99 lei = 0.73508 lei
o9 ml cold water costs: 9 ml / 500 ml x 2.59 lei = 0.04662
o6 g unsweetened cocoa costs: 6 g / 100 g x 3.00 lei = 0.18 lei
o25 g sugar costs: 25 g / 1000 g x 4.29 lei= 0.10725 lei
o25 ml water costs: 25 ml / 500 mlx2.59 lei= 0.1295 lei
o17 ml milk costs: 17 ml / 1000 ml x 5.49 lei= 0.093 lei
o2 ml vanilla costs: 2 ml / 20 ml x 2.60 lei = 0.26 lei
TOTAL: 0.182 lei + 0.0017 lei + 0.73508 lei + 0.04662 lei + 0.18
lei + 0.10725 lei + 0.1295 lei + 0.093 lei + 0.26 lei = 1.73515 lei
= approx. 0.39 euro = approx. 1.63 zloty

10. Ingredients needed for our group (2 portions), in
grams:
flour: 52 g x 2 = 112 g
salt: 1 g x 2 = 2 g
butter: 23 g x 2 = 46 g
cold water: 9 ml x 2 = 18 ml = 18 g
unsweetened cocoa: 6 g x 2 = 12 g
sugar: 25 g x 2 = 50 g
water: 25 ml x 2 = 50 ml = 50 g
milk: 17 ml x 2 = 34 ml = approx. 34 g
vanilla: 2 ml x 2 = 4 ml = approx. 4 g

11. Baking temperatures in ˚ Farenheit:
(˚ F = 9/5 x ˚C + 32)
1. 210 ˚C = 9/5 x 210 + 32 = 378 + 32 = 410 ˚F
2. 180 ˚C = 9/5 x 180 + 32 = 324 + 32 = 356 ˚F
The ratio between flour and butter:
520 g / 190 g = approx. 2.74

13. The average cost of the piece of pie in all the cities
that take part in this project:
(1.73515 lei + 2.48 lei + 2.88 lei + 2.41 lei + 1.58 lei +
2.83 lei + 2.69 lei) / 7 = approx. 2.37 lei = approx. 0.53
euro = approx. 2.23 zloty
The difference between the average cost and the cost
in Bucharest:
2.37 lei – 1.73515 lei = approx. 0.63 lei

14. How we had fun:

15. After baking…
The pie was really tasty! The dough was crispy, like a cracker, and
the topping was like chocolate pudding… Delicious!
