An experiment by Heinzmann was said to show that a normal frog would not attempt to escape if the water was heated slowly enough,   which was corroborated in by Fratscher. InProfessor Douglas Meltonof the Harvard University Biology department, said, "If you put a frog in boiling water, it won't jump out. If you put it in cold water, it will jump before it gets hot—they don't sit still for you. Zug, curator of reptiles and amphibians at the National Museum of Natural Historyalso rejected the suggestion, saying that "If a frog had a means of getting out, it certainly would get out.
Published August Update: September Our winning Cuisinart 4-quart slow cooker has been discontinued by the manufacturer. We reviewed its closest replacement, the Cuisinart 4-Quart Cook Central 3-in-1 Multicooker and incorporated it into our results chart.
How we tested We used to turn to our slow cooker only when we were cooking for company or making a big batch of stew meant to last for several meals our favorite model holds 6 quarts. But these days, many manufacturers are selling smaller models, too, offering the same set-it-and-forget-it convenience to small families—or for small kitchens.
For comparison, a 6-quart slow cooker can fit eight chicken thighs or more; smaller cookers fit about four thighs. One model lets you brown food right in the pot rather than in a separate pan and doubles as a rice and risotto cooker.
Another has a latching lid so that it can travel without spills. Slow cookers are designed to cook food gently over a long period of time. Such low-and-slow cooking turns tough meats tender and succulent and produces flavorful sauces and stews. We looked for a model that would heat up quickly to get food into the safe zone and then maintain a simmer; according to the U.
A good slow cooker should also produce perfect results on both low and high settings, and in recipes with lots of sauce or very little. For our first test, we made chicken thighs in a hearty tomato sauce, a recipe that has plenty of liquid and cooks on high for 3 to 4 hours.
All but one of the cookers easily reached a safe degrees in less than 2 hours. And even after 5 hours that same problem cooker—plus one other model—failed to bring the chicken to doneness degrees.
The other models produced juicy chicken in nice thick, chunky sauces. Next we made smothered steaks for two, which braise for 4 to 5 hours on the high setting with a moderate amount of liquid. Here one of the models that had struggled in the previous test produced tough, chewy steaks; two other models ran hot and scorched the sauce.
But the rest performed well. Pushing our slow cookers to the max, we ran an extreme test: Only two of the cookers yielded juicy, tender ribs.
The two models that succeeded had also aced the chicken and steak tests. Some cookers shot up to the boiling point of degrees and maintained a roaring boil throughout the tests—these were the very models that overcooked ribs and scorched steaks.
Each subsequent time that we tested this particular model, it behaved differently.
We ordered additional copies of the same model and repeated our tests. The copies performed no better. The best slow cookers reached degrees quickly and then slowly climbed over a period of hours.
With these models, foods reached safe temperatures and then simmered gently to tenderness. Which models were easy to use? The shape of the inserts mattered less.
Although food fit slightly more easily in oval inserts, round and oval cookers performed about the same. In fact, we had one of each for our two top performers. That said, a cooker with an especially spacious oblong insert burned the sauce for the ribs and the steaks.
In the end, we can recommend two small slow cookers.
Our winner was simple to set, and its digital timer meant that we could just walk away. It cooked food well if a little more slowly than other models. If your kitchen is cramped, be aware that it is nearly as big as a full-size slow cooker.
Our Best Buy, with manual controls and no timer, was far less convenient, but it performed perfectly. Enter your email address Click to Start How we use your email address America's Test Kitchen will not sell, rent, or disclose your email address to third parties unless otherwise notified.

Slow-Cooker Mashed Potatoes. For evenly cooked potatoes in the slow cooker, we use a small amount of water and a parchment shield to create a moist, steamy environment. Thinly sliced potatoes cook more evenly than chunks, and boiling the water first jump-starts the cooking process. America's Test Kitchen will not sell, rent, or disclose.
Line a slow cooker with an aluminum foil collar and lightly spray with vegetable oil spray. Microwave ziti and oil in a bowl at 50% power, stirring occasionally, until some pasta pieces look toasted and blistered, about minutes.
The boiling frog is a fable describing a frog being slowly boiled alive.
The premise is that if a frog is put suddenly into boiling water, it will jump out, but if the frog is put in tepid water which is then brought to a boil slowly, it will not perceive the danger and will be cooked to death.
After four hours, the liquid in the slow cooker should be boiling. Carefully remove the chicken thighs, making sure to replace the lid quickly, shred the meat, and stir .
