There are some basic fundamentals that need to be followed and as long as you stay within those boundaries then I guess a recipe is just as good as how much you like the product!
To consistently deliver the same product, then you get into the process side of things.
What I mean by basic fundamentals is that you start with the principle that you're going to have 4 ingredients as the starting point of the beer and that base malt is going to account for the majority of the malt bill, malt and hop quantities are going to be reasonable for the size of the batch and you're going to pitch enough yeast for it to ferment properly, then you cant go far wrong.
Don't follow these fundamentals and yes, even without talking about chucking in ginger, jalapenos or anything else, you can have a very bad recipe!
To test this theory, try using 20lbs of black malt in a 5GL batch , boil it with half a pound of warrior hops added for 90 minutes... and then ferment it out with half a packet of US-05 and see what kind of beer you get haha
