Okay guys, this is going to be quick.
Let me introduce "Mustard"
Awe, how sweet, they like each other...
.. and they become one.
Wow. That's amazing. Please don't buy the pre-made stuff, please? Okay, it's really up to you, if you really like spending money on stuff you already have, only to have it sitting in the fridge until it's so old that you end up throwing it out. Feel free to venture outside the box and use different mustards and syrups too.
Add some apple cider vinegar and onions, and you have yummy way to cook a pork roast in the slow cooker.
