A Piece of Pie in....
A collaborative task in the eTwinning
project A Taste of Maths
The Recipe
Ingredients for 10 portions
For the dough
* 1,75 cups flour
* a pinch of salt,
* 3/4 cup margarine/butter cut into small pieces,
* 4-5 tablespoons of cold water.
For the filling
* 6 cups of apples cut into cubes,
* one cup sugar
* cinnamon or other spices if you prefer
One cup = 250 grams
One tablespoon = 20 grams
The Recipe
Preparation:
Mix the flour with salt, then with pieces of margarine / butter
and then gradually add the water. When you got a dense and
uniform mass of dough, form a bubble, wrap it in foil and put it in
the refrigerator for an hour.
After you take the dough out of the refrigerator, divide it into
two parts and turn each of them into a round flat sheet slightly
larger that the diameter of the baking pan.Take one round tart pan
greased well with butter or margarine and place the first sheet
insde (it should be big enough to cover the margins), then pour the
apples over the dough.
Then put a second sheet over the apples and carefully apply
pressure on the margins with a fork to make them stick together.
The pie is to be baked for 15 minutes at 210 degrees C, then
for 40-45 minutes at 180 degrees C.
The Tasks
1. Calculate the ingredients you need for the
number of portions according to your group, in
grams.
2. Calculate the ratio between the flour and the
butter.
3. Calculate how much a portion of the pie
would cost- show us your calculations and the
unit costs for each ingredient.
The Tasks
4. Calculate the baking temperatures
assuming your oven is labeled in Farenheit,
not Celsius.
Use the formula F=9/5*C+32
5. Optional: bake the pie and show it to the
partners!
Piece of pie, isn’t it?
Enjoy the task, and
the pie!
