Angel Cake

Assalamualaikum... Hi everyone...This is our first experiment which is Angel Cake...




OBJECTIVE
  • Making an angel cake with optimum texture, volume,and tenderness.
  • Evaluate angel cake according to accepted standards.
  • Relate the effect of mixing to the texture,volume, and tenderness of angel cake.
  • Explain the role of cream of tartar in an angel cake.
  • Interpret the effect of sugar on flavor, tenderness, volume, and texture of angek cake.
  • Describe the interrelationship of sugar ( or alternative sweetener ) and gluten development in angel cake.
  • Relate the effect of foam development on texture, volume, and tenderness of angel cakes.
  • Explain the influence of baking condition in determining quality of angel cake.
  • Compare the merits of all purpose and cake flour in preparation of angel cake. 

This is the basic ingredient for making Angel Cake..

15g Cake flour 
 10g Sugar
41g Egg Whites
32g Sugar
0.6g Cream of tartar
0.1g Salt

METHOD:-
  • Preheat oven to (350F (177C) except for procedure 6, which has seperate baking directions.
  •    Line the bottom of each individual loaf pan (5" x 21/2"x2") with wax paper cut to inst fit. Do not grease the sides of the pan.
  • Sift flourand first weight (10g) of sugar together and set aside.Beat the egg whites to gether to the foamy stage, using an electric mixer ( same kind for all parts of the experiment).
  • Unless indicated differently in a specific series, add the cream of tartar and salt.
  • Continue beating on the fastest mixer setting while gradually adding 32g sugar. Beat the whites until the peaks just bend over.
  • Sift 1/4 of the flour-sugar mixture over the whites. Fold in gently with 10 strokes using rubber spatula.Sift the second 1/4 of the flour-sugar mixture over the whites and fold in gently with 10 strokes, followed by the same process for the third addition.
  • Sift the final 1/4 of the flour-sugar mixture over the foam and fold 20 stokes to completely blend the mixture (making a total of 50 folding strokes with the rubber spatula). 
  • Gently push and weight 100g of the batter into a pan. Finish all of the cakes being baked in one oven before placing them all in the oven at the same time.
  • Bake until the surface springs back when touched lightly with a finger (-30 minutes). Record the baking time. 
  • Cool in an inverted position with air circulating under the pan. When almost cool, remove from the pan.  
Before start Chef Zaid give task to  each  group  to complete this experiment. So we divide the task to the group members.

1) Double cream of tartar- prepare the basic formula, but use double , (1.2g) cream of tartar.

3) Decrease cake flour - Prepare th basic formula, but decrease cake flour to a total of 10g.

 Ingredient


This also same with the other, but this time we decreased cake flour to a total of 10g.


Fold 10 stokes ( untill 50 strokes)


 

 Before Bake


After Bake

After finish bake we record the baking time.We cool it first in an inverted position with air circulating under the pan. When almost cool, remove it from the pan. Than we record exterior color and shape, texture, tenderness, volume before bake and after bake.

 The result of all the angel cake with different task that give by chef ..
