A Waring Pro BFS50B Professional Buffet Server and Warming Tray is very well made, looks great, and works rightly. It is pretty flexible to use as a flat tray. It can hold quite a bit of food as well. The size is just right for either a meal for most likely at least 15 people or just snacks for a big party.
You can of course serve less by either placing less into the containers which come with the server, or restoring the containers which come with it and serving a smaller portion in foil pans in the warming tray.
You can put the Waring Pro BFS50B Professional Buffet Server and Warming Tray to an extreme test for the first use as you prepare all of the food for a 10-person race crew in a 20-hour endurance road race. You can cook all the food ahead of time but do not use this item to cook the food as it will not get hot enough to be safe. You can use this server to reheat and then serve hot food to the crew around the clock.
Firstly, you can use the tray alone with tamales and also tortillas wrapped in foil until they become hot. Then, put the 2.5 quart containers in to heat and then put half rice and half refried beans. While heating, turn it to the high and in place of the plastic lids, cover the containers using foil and set the warmed tamales and tortillas on top.
The tamales and tortillas will stay warm, and the Waring Pro BFS50B Professional Buffet Server and Warming Tray gets the beans or meat hot in an hour. As it is hot, change the temp to low, then put on the plastic lids, and is still capable of balancing the tortillas and tamales on top to stay warm.
The crew eats in shifts, and the server keeps the food hot all night, with a little stirring in order to keep the heat even. You can see that the lid design can cause enough condensation to keep the food wet, even after some hours, nothing dried out.
Lastly, you can see that the metal pans of this Waring Pro BFS50B Professional Buffet Server and Warming Tray are very easy to clean. The containers are not nonstick officially and do not have that Teflon kind coating on them, however they are still easy to clean. You can use it for hot dips, and also party foods like hot wings, mozzarella sticks, Jalapeno poppers, and meatballs.
