Flash-forward 18 years, and dishwasher cuisine seems to be making a comeback.

Here's How To Poach Salmon In The Dishwasher

A handful of YouTube videos and food blogs are showing off the method. And even Oprah offered up a recipe for an entire lunch — noodles, asparagus and salmon — prepared in the dishwasher.

So how does it work?

You wrap the salmon tightly in aluminum foil or a cooking bag. Add a lemon wedge, oil and some spices — cilantro, ginger or really, anything that you want. Put the foil package on the top rack and start a normal washing cycle, without adding soap.

That's the traditional method. And it works great. The hot water and steam essentially poach the salmon. And at the low temperature, about 140 to 150 degrees Fahrenheit, the fish cooks very slowly, so it turns creamy and soft, as Dan Pashman of the Sporkful podcast tells Weekend Edition Sunday host Rachel Martin.

But is this really worth the time and energy? Running a dishwasher uses a lot of electricity and water. And if you're not adding soap, then you still need to repeat the wash to clean greasy pots and pans. Seems like just a gimmick to impress dinner guests, right?

Not quite, says Italian food writer Lisa Casali. She argues that the method can be quite environmentally friendly. There's just one trick: Instead of using aluminum foil, as many websites recommend, you should put the food into airtight canning jars or food vacuum bags. Then the hot water doesn't touch the food. So you can add soap to the cycle and really clean your dishes while poaching dinner.

Casali has been experimenting with dishwasher cuisine for a few years. And the result is her cookbook Cucinare in Lavastoviglie (Cooking with the dishwasher), which gives recipes for a whole array of dishes, like couscous, veal, tuna and even fruits and desserts.

Dishwasher cooking is best for foods that need to be cooked at low temperatures, Casali says. "After some experiments, I found that it wasn't just a different way to cook — it was a really particular technique," she says. "Something I was looking for years: the way to cook at low temperature at home."

Unfortunately, Casali's book appears to be available only in Italian. But the innovative chef has put together a few how-to videos on Vimeo, with English subtitles, describing top recipes.

Or you can watch Pashman on YouTube cook everything from shrimp and beef to spinach and pears in the dishwasher. Bon appétit!
