You can try a small Batch taste it cold, then simmer and taste the difference. I don’t simmer mine, but you may prefer it. You also may want to add other flavors, but get the base down first that you like, write that down, then rewrite a new separate sheet with the basics and add what else you want. Herbs, citrus, worshestershire , onion, mustard whatever floats the boat, but don’t do them all at once. Get your base dialed in, then add a couple things and no more at a time. I make a list of ingredients that don’t work. Saved me more than once but you won’t know till you try.
