EGGSELLENT EGG WHITES

Does the size of the bowl affect the time it takes to whisk egg whites and sugar to the desired consistency to make meringue?

The process...

My Prediction

I hypothesize that the bigger the bowl the longer period of time it will take to whisk the eggs whites and sugar to the desired consistency to make meringue. I predict this outcome as I believe the bowls with the largest surface area, the bigger bowls, will take longer for the egg whites and sugar to combine and therefore reach the desired consistency, unlike the smaller bowls that have a smaller surface area meaning the ‘mixture’ would circulate the bowl rapidly and evenly and thus reach the desired consistency at a faster rate.

RationaleThe question was selected due to my own curiosity when cooking meringues. It has been previously noted through various other investigations that the type of bowl, that is, glass, copper, plastic or enamel, plays a role in how well egg whites are whisked. However, I was unaware of any results demonstrating whether the size of the bowl would also play a role in the time it takes to whisk egg whites and sugar to the desired consistency to make meringue. This interested me; I hope to find the most time efficient method of whisking egg whites.

The findings aligned with the hypothesis; the bigger the bowl the longer period of time it will take to whisk egg whites and sugar to the desired consistency to make meringue. However, I did not predict the rate at which the times would increase; evident in the results table (see table 1.1) the difference between the white and the light blue bowl is only 25 seconds where as the difference between the dark blue and red bowl is 5.31 mins, I found this dramatic increase interesting, this may encourage a further investigation within the parameters of the classroom. Have a look the finished result too!!! For further reading, take a look at my references.

Results

What I found...

Step 1: Weigh the sugar and put aside. Step 2: Take the eggs out of the fridge and separate, place the egg whites in the appropriate bowl; white, light blue, green, dark blue or red. Step 3: Place the electric mixer in the egg whites and turn up to speed 5 whilst simultaneously turning on the stopwatch, move the electric mixer in a clockwise direction. Step 4: As the stopwatch displays 5 seconds pour all of the sugar in. Step 5: Continue whisking the egg whites and sugar in a clockwise direction.Step 6: Observe the mixture until it reaches the desired consistency; turn off the electric mixer and stopwatch, turn the bowl upside down and observe.

Would this experiment work in a primary school context? Have a look at what I think by clicking here!!!

Have a look at the photos of this fair test. Made some mess, but at least I got to lick the bowl!
