Enough Beer to submerge them, Thyme or Rosemary, a teaspoon of mustard powder, and a wee bit of garlic for 24 hours. Salt and Pepper just before I put them on the grill.
I forgot to mention, the marinade must be alcohol-free. Even if parts or all the alcohol evaporates during preparation, alcohol won't be used. Can beer be substituted with another liquid?
Coca cola is amazing for pork... when grilled it gives it an amazing light crust that can induce multiple tastegasms. I had it in Paris last weekend and thought I'd died and gone to culinary heaven (everyone who tasted it thought it was amazing).
Juice of 1 lemon, 1-2 cloves crushed garlic, chopped up fresh rosemary and sage, a little olive oil, salt and pepper. Whisk. up and pour over the chops in a tupperware box. Put the lid on marinade for as long as you - hours, overnight etc. Pick up the box and shake it now and again.
