Start by mincing or grating the garlic. The smaller the better, I say, but you will find some recipes for how to make a garlic butter sauce that call for chunks of garlic. Which way you go is up to you.
Next, place the garlic into a frying pan and add some better to it- just enough to grease the pan with. Cook on medium heat until you can smell the garlic cooking. You want it golden colored but not dark brown or black. It should not be burnt when you take it off the heat. My method to making sure the garlic doesn’t burn is to cook it for about 45 seconds only and to stir it while it cooks.
Add in salt, lemon juice, garlic powder and the rest of the butter. Combine in the frying pan and cook on low heat to melt the butter and combine smoothly.
Take the butter off the heat and add in the parsley. Stir slightly to mix it in.
