【How-to】How do you make a1 sauce from scratch

I use A1 for steaks, chicken, pork, fries, baked potatoes, cauliflower. If it can be eaten as a side to meat, generally I’ll put A1 on it. And if it’s meat, but not bacon or ribs, I’ll put A1 on it. And if it’s a savory breakfast food, like eggs, I’ll put A1 on it.
