Investigating on how to bake a cheesecake, I found a video on youtube that explains how to make it. First of all, the instructor says that we must have three eggs lightly beaten, three 8-oz packages cream cheese softened, one third cup of sugar, one cup of sugar, half gram crackers, crushed, two tea spoons all purpose flour, one tea spoon vanilla, a quarter cup of milk, and on third melted butter. However, in the video, she does not specify what kind of crackers we must use, and also she does not explain what the role of the ingredients that she uses to make the cheesecake is; what kinds of cup and finally, I think she should notify all the materials we need to bake at the beginning. On top of all, her documentation was fair since if we try to follow every step she mentioned in the video, we will be able to make it.
