Welcome Alana. You came to the right place for advice. And like the others have said, don't ever b e afraid to ask questions. We have professional chefs on this board all the way down to people who have never cooked a single thing and every single one of us can still learn from each other. The more questions you ask the more you will learn.
Kitchenelfs recipe sounds great (as all of her recipes do
). For burgers you can get as complicated or simple as you want. You will find burger recipes that have tons and tons of things in them and others that are just very simple.
The most simple way to make a burger is just forming ground beef into patties and cooking. You really don't need anything else other than maybe a little salt. When I make them this way I do not use very lean meat. I try to use ground chuck which is about 70-75% lean. The fat content will give flavor to the burgers and also help to keep them from drying out. Just take the meat and add a little salt then form into patties and cook.
One important thing to remember when cooking them, and I can't stress this enough, is to not smash the burgers down with the spatula. You always see people on TV do this or in fast food joints. It sounds great when you hear that sizzle, but it is the worst thing you can do to a burger. What happens when you press it down is that you are squeezing out all the juice. The sizzle you hear is the juice hitting the hot pan (or flame). The burger will cook faster if you do this, but it will not be as juicy. I also only like to flip my burgers once. You should not have to flip it multiple times.
Good luck with your burgers. I am sure you will do great. Make sure to come back and tell us how it turned out
