Whisk eggs without an electric whisker I am planning on baking Macarons.   The recipe requires whisking egg whites in an electric whisker but I don't have one. It is bit expensive to buy a good one for me right now and I do not have space in my kitchen to actually keep a machine like that.  

I was wondering if there was any other way of doing it.  

I don't know if beating eggs by hand would get the same result as it is supposed to be very fluffy.

Also I have an electric mixer in which I usually whisk eggs for a cake. My mixer is the one where I can press the button to create short pulses so it does not overdo the process. Does anyone know if I can use the same mixer to beat egg whites to the same consistency as an electric egg beater?  

Any advice is appreciated.
Yes, you can whip egg whites (or whipped cream, or....) by hand. There are a few things you need:


a reasonably large bowl
a good, sturdy whisk, again not too small
proper technique
a good amount of ellbow grease
patience


It will typically take longer than when using a mixer (for beginners, I've seen pros that could keep up with any measly old mixer, especially taking cleanup time into account) but lets you control the outcome better: less chance of overmixing or uneven results.

I myself have done it several times, either because I had no mixer at hand or because I was working in the middle of the night and didn't want to wake everyone and the neighbours.
