I'd like to generate a discussion on water pans. After reading Meathead's "How to Use Drip Pans and Water Pans, What to Put in Them and How to Clean Them" article, I learned a lot in general about water pans. Thank you, Meathead! There are 8 reasons discussed in that article about how drip pans can help during the cook.
Regarding reasons 1 through 3: I use a medium Big Green Egg equipped with a Flame Boss 200. The Flame Boss has made controlling the pit temperature very easy. Therefore, I do not necessarily need the benefit of the water pan to assist in temperature regulation. The plate setter blocks the direct heat from the coals from scorching the food. Therefore, I do not necessarily need the water pan to assist in blocking the direct heat from the coals.
I do, however, like the idea of the water pan for reasons 5 through 8 discussed in Meathead's article. Those reasons generally relate to helping the smoke stick to the meat and improving flavor, as well as increasing the cook time due to evaporative cooling which give the fats and collagen more time to melt.
I suppose one theoretical downside to the water pan is that it takes some of energy supplied by the burning fuel, thereby decreasing the efficiency of the cooker. The benefits of the water pan may outweigh this downside, howerver.
I've only had the Big Green Egg for a few months and I have not had enough time to do some controlled experiments of cooking meat with and without a water pan keeping all other variables equal. I will update this topic once I collect the data.
Anyone with strong feelings one way or the other regarding water pans?
Thanks, and happy grilling!
