Using accurate digital thermometers to monitor cooking and internal meat temperatures is essential to being all that you can be in the backyard. Unlike the caveman-era heat estimators built into the lids of most grills and smokers, modern pellet smoker LED displays will give you the real story of what's happening in your smoker. Of course, if your smoker doesn't come with a dual-display system that monitors both cooking and meat temps, you'll still need an accurate digital meat thermometer.
The biggest cleanup issue is the buildup on the heat deflector under the cooking grates. You'll need good gloves and an apron. On most models, a thorough cleanup means a 30 minute process of taking out the greasy grates and the gooey deflector plate, scraping them and washing them. You should do this when the carbon and grease cover the deflector plate. Stainless parts can go in the diswasher, but I wouldn't do it. That grease is like tar and it could get all over the insides of the dishwasher and hang on for dear life. I use a handheld steamer like the Steamfast SF-320 Portable Steam Cleaner shown here.
One of Yoder’s most unique features is the Variable Displacement Damper. This makes it easy to smoke, sear, and grill your food using the YS640. This is a metal plate that moves along the lower smoke box. If you move it all the way left, it concentrates heat directly over the firepot for conductive searing. If you move it back to the right, the heat will spread evenly across the entire some box for even cooking. The unit comes with a side firebox which has a removable cooking grate if you want to grill your food in it.
Also own a Big Steel Keg which I love! Didn’t want an egg or a Primo while I was up north WY & CO as I had to many friends complain about cracking when trying to use them in cold weather! Many times at Thanksgiving or Christmas I have cooked on any or all of these devices at -5 to -10. It can be done but with a strong wind it is quite a challenge! My Weber (been thru a couples) and my Keg still have high ratings for great steaks and burgers. But for low and slow you are pushing it to get there and my friends with the ceramic style units say it takes some practice and close attention. What I don’t like about and Egg or my Keg is if you do need to end up feeding the fire on a long cook it is a real serious challenge!
