LOL.Some day, and that day may never come, I will call upon you to do a service for me. But until that day, consider this a gift.
Sure. Start with a stick of real unsalted butter. This will make only a small amount so you won't be wasting too much when you f it up the first time.
Melt 3/4 of the stick over medium heat then add about an ounce of clam juice, 1/8 teaspoon of creole or cayenne, about a 1/2 teaspoon of diced onion and a minced clove of garlic. When the garlic gets soft, add the rest of the butter.
May need a little more or less of any of the above to satisfy your palate.
That should get you started.
Just remember going in, you will never get it exactly as you remembered it being at the restaurant you first had it. Maybe close or even better, but you can get it to where you can make it for friends and family and impress them.
The clam juice is key, and imo so are the green onions for garnish.
Try a drizzle of sriracha as a finishing touch.
