I dry brine with just salt and then use an herb-infused butter for moisture and flavor
Oh I say the butter is a great idea. You can't have too much flavor and moisture in roasted meat in my humble opinion 🙏🏼
But like regular butter.
I personally would still do the butter id also do like garlic and onion powder on the skin to make it extra yummy It always comes out so yummy!
I agree with Mandie that you can’t have too much flavor and moisture. You should be fine with both the brine and butter having citrus. I make an herb butter with salt, pepper, olive oil, onion powder, lemon zest and juice, crushed garlic, and parsley. Put it in between the skin and meat
