For the taste and texture, you will have really delightful buttery little cakes that are slightly airy but still with an amazing bite to it. It can easily disintegrate into your mouth quite effortlessly, as easy as it is to enjoy these delights!
You can definitely achieve either a chewy or an airier texture depending on your liking. I will share this under the method part of my sharing which brings me to the next point.
For the method of preparation, I would strongly recommend either a handy handmixer or some elbow grease. I honestly prefer the former, a handmixer. I am not so sure if my hands are sore from all the writing for my assignments, but even using a handmixer makes my hands slightly sore.
This is because you will be beating the batter for up to 10 minutes with a handmixer (and much longer with elbow grease!). Nonetheless, both should give the same outcome and it is pretty much up to personal preferences as well as the equipment you have on hand (i guess a hand is an equipment too!).
Refrigeration here is crucial. I have yet to find the science and reasoning behind it but if you do have it, send it over!
I do realize, however, if you do refrigerate it for too long, you will have a dense outcome. So this is up to you on how you would like it!
