Here's my Honey-Mustard marinade recipe that goes really well with American-style BBQ pork ribs.
1 cup Dijon or any other full grained mustard
1 cup honey
1 clove crushed garlic
1 tablespoon of olive oil (extra virgin)
sprinkle of Worcestershire sauce (Soy sauce works well as a substitute).
pinch of sea salt (don't add the salt if using Soy Sauce)
sprinkle of mixed herbs (Rosemary , Garlic, Marjoram, Thyme, Oregano, Mint, Basil) aka Masterfoods Lamb herb mix here in Australia (

Mix together in bowl, add additional mustard, honey or oil as needed to soften/thicken as needed.
Coat pork ribs and leave in fridge for 2-3 hours. (Longer if you like the mustard flavour).
Fire up your BBQ (I use a traditional Charcoal Weber BBQ), and cook ribs turning once or twice only.
Also as a side, try sweet potato (or known as "yams" in the US) slow roasted on BBQ as well, served with sour cream and whipped butter. Add a garden salad in as well.
This is a great one while watching the footy/cricket with mates on the weekend!
