Where can I buy a good barbeque mop?
I'm sure you'll find lots of places just googling for barbeque. That's how I got mine. But I have found this to be one of the most useless items I've ever bought for cooking. It gets completely loaded up with the sauce (like a pint goes into the fibers - what a waste), and cleaning is a major hassle. If you're doing a whole pig on a spit, or something as large, I suppose a good mop might be useful. But whenever I want to finish my spare ribs or brisket wet, I just use a basting brush.
I couldn't agree more...a mop is one of those things that you need to use a LOT, or else you'll end up thinking, "What a waste THAT was!" If you're doing a whole pig, or several racks of ribs several times a week or otherwise doing tons of meat, a mop is a good investment. Otherwise, just get a good (silicone - you can toss it in the dishwasher) pastry brush and make do.
Actually I like the Martha Stewart ones available at WalMart (or they used to be available there). I don't find them that hard to clean as I usually just soak in a white vinegar/hot water mixture or something similar when I'm done. Since my mop sauce for my ribs and shoulder are generally cider vinegar based, this works well for me.
