We can’t buy and review everything, but luckily Consumer Reports can. They have recently reviewed the Masterbuilt Butterball Professional Series Indoor Electric Turkey Fryer. It can also be used as a steamer.
Remarkably, it’s designed to hold a turkey weighing up to 14 pounds… although they tested it with a “snugly fit” 12 pounder. Getting it up to cooking temperature was a little slower than I have found with gas, but it uses less oil (2 gallons as opposed to about 3).
Their conclusion? It failed as a steamer, but worked well as a fryer. Their test turkey was brown and very juicy, but created oily thighs. To me, this would be a sign that the temperature was not hot enough, but an electronically controlled thermostat should have taken care of that.
Their full review can be found at Consumer Reports and a video of the ordeal–that seems goofy when you think of how respected they are–is below.
