One of the best accessories you can buy for smoking is a couple of 5 gallon buckets with lids. You can get them at Lowes or Home Depot for about $3. Line them with a small trash bag and put your brining mixture in it then add your meat, pork butt, shoulder, ribs whatever and put the lid on. Stick it in your fridge and let it sit for at least 24 hours. In larger cuts of meat you can also inject some of the brining solution into the meat after it comes out of the bucket.
You don't actually need the trash bag, I just use them because it makes clean up easier
That makes a lot of sense, what if my fridge is too full to fit the 5 gallon, are there smaller buckets that would also work?
