A piece of pie in

  1. 1. A Piece of Pie in… …Our Towns
  2. 2. A collaborative task in the Comenius- eTwinning project “AIMS- Alternatives for Innovative Math Study”
  3. 3. Ingredients for 10 portions: For the dough:      * 1,75 cups flour      * a pinch of salt,      * 3/4 cup butter cut into small pieces,      * 4-5 tablespoons of cold water. For the fillling:                * 3 tablespoons unsweetened cocoa              * 1/3 cup flour               * 1 cup sugar                                                 * 3 egg yolks               * 1 cup water                                                 * 2/3 cup milk               * 2 tablespoons butter                                    * 1 teaspoon vanilla (or similar) The Recipe
  4. 4. Preparation      Mix the flour with salt, then with the butter and then gradually add the water. When  you got  a uniform mass of dough, form a bubble, wrap it in foil and put it in the  refrigerator for an hour.      Mix cocoa and flour over hot water and whisk in about half of the 1 cup of water,  just enough to make a smooth paste. Blend in the sugar and the beaten egg yolks and  add remaining water and milk. Cook over low until the mixture is thick; add butter and  vanilla.         After you take the dough out of the refrigerator, turn it 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 sheet insde (it should be big enough to cover the  margins).The  pie  is  to  be  baked  for  15 minutes at 210 degrees C,  then  for  40-45 minutes at 180 degrees C.      Pour the filling into the baked pie crust. Chill thoroughly.  The Recipe
  5. 5.  Calculate the ingredients you need for the number of portions according to your group, in grams.  Calculate the ratio between the flour and the butter.  Calculate how much a portion of the pie would cost- show us your calculations and the unit costs for each ingredient.  In the end, create a bar chart with the cost of the same piece of pie in all the partners’ towns. One cup = 250 grams One tablespoon = 20 grams The Tasks
  6. 6.  Calculate the average cost and the difference between this and the cost in your town.  Calculate the baking temperatures assuming your oven is labeled in Fahrenheit, not Celsius. Use the formula F=9/5*C+32  Optional: bake the pie and show it to the partners! The Tasks
  7. 7. Don’t forget to take photos so we can see you at work! Piece of pie, isn’t it? Enjoy the task, and the pie!
