Cooking food is something that usually requires a lot of different types of skills at this current point in time. One of these skills would be patience due to the reason that you would need to wait a long time before you have the level of experience necessary to cook food in a way that would make it completely, utterly and undeniably palatable to anyone fortunate enough to place said food within the orifices present on the front of their faces which most people would refer to as mouths.
Buying a commercial deep fryer can help you cook incredible food without a shadow of a doubt, but you might also want to learn about what the best food is for you to cook within the confines of such an incredible kind of device. Chicken is usually considered to be the best of the best in this regard, and as a result of the fact that this is the case you should at the very least try to make some deep fried chicken once you have such a fryer in your possession and after you have set it up in your home.
Try to cover the chicken in a mixture of egg and flour so that the skin becomes really crispy. This has the added advantage of making the chicken incredible juicy as well since it would lock all the moisture in and prevent it from escaping into the oil which would not just make your chicken dry it would also ruin the oil which you could very well have reused since it would have been perfectly fine had you not made such a grave error that ruined pretty much everything.
