While we normally don’t eat large quantities of bananas because of the high starch and sugar content, we occasionally make exceptions for finger bananas, so on an impulse last week, when I encountered bunches of them at a local market, I bought one bunch (about 20 bananas). Initially they were still a bit green, but as the week progressed they continued to ripen, and we were just not eating them fast enough.
Faced with the prospect of possibly having to throw them out, I remembered that some years ago I bought a dehydrator with the intent of making beef jerky. Intent and reality never collided, and the device sat in our storage room collecting dust. Until now, as I realized this would be a perfect way to save the bananas from premature extinction.
It was a match made in heaven.
What a dehydrator does is blow warm (or hot) air down over trays of food. The warm air evaporates or dehydrates the moisture from the food, effective drying it out. Very simple process. The particular dehydrator I had was made by Open Country, targeted primarily at folks who hike around a lot and want to carry food with them that weighs less than normal (considering I probably bought this at a outdoor sporting store, it makes sense).
After carefully reading the manual, I sliced up all the bananas, placed them on the dehydrator’s trays, set the dehydrator’s temperature to 135°F (the temperature suggested for fruit) and let the device do its thing for the next 8 hours, after which we had dehydrated banana slices.
The dehydrator, as part of the process of forcing moisture out of food, ends up shrinking the food item being dehydrated, which in turn concentrates the flavor. So, the dehydrated banana slices were sweeter and more flavorful than regular moist bananas.
I felt inspired now, having realized how stupidly easy it was to use the dehydrator. So, next I got some lean roast beef (raw), sliced it in quarter inch thick strips against the grain, and then marinated it for half a day in a mixture of ketjap manis, sambal oelek, garlic, vinegar, and water.
I then dehydrated the beef for eight hours at 155°F (recommended for meat), and voila! Beef jerky! After it cooled, we found the beef jerky to be a bit drier than desired. Next time I think we’ll try for 6 hours and see if that makes it a bit moister. But it tasted great, and there was no question that it was fresh beef jerky.
My next effort was to make low-carb chips using daikon radish and eggplant slices, using the dehydrator to eliminate most of moisture so I could more easily fry the slices in my fryer. That worked moderately well, but the four hours they spent in the dehydrator were again a touch too long. What was interesting was that the daikon radish also got bitter after being flash fried, but was incredibly “radishy” tasting out of the dehydrator.
Yesterday we found fresh strawberries at our local market (not a common occurrence here on Bonaire – we’re usually stuck with frozen berries), as well as fresh blueberries (an even rarer happening), so we sliced up one box of strawberries, put them on the dehydrator trays, and dried them out. Krystyana added a handful of blueberries to one of the trays too.
Again, four hours was too long for the strawberry slices – they were completely dry, but powerfully flavored. I plan to take advantage of that dryness to make a potent and flavorful strawberry powder in my blender. The powder can then be used in cooking, as an additive to yogurt or cream, or anything else a strawberry-loving heart desires.
The blueberries were in for 13 hours, and were still overly moist and kind of bland – no doubt due to the fact the skins have not been punctured to assist the escape moisture. I don’t think we’ll try whole berries again. Cutting them in half might have been better.
The kids devoured the original batch of beef jerky, so last night we worked together to marinate two batches of beef – one in a chipotle, brown sugar, chili powder, garlic, and vinegar marinade, and the other in a lemon grass, cumin, soy, brown sugar, and fish sauce marinade. They went in the dehydrator this morning, and four hours later the thinnest slices were ready, and all the meat was properly dried (not overly so) after six hours. Both were delicious.
The kids are already talking about what flavors of jerky they want to make next. And in the process both have been learning about better knife use as well as selecting appropriate cuts of beef (for jerky it should be quite lean).
The manual for the dehydrator also suggests that you can dehydrate sauces like spaghetti sauce for later hydration, or something like apple sauce in order to make a fruit leather that can be rolled up in wax paper and eaten later as a snack. We might try something like that soon.
If you don’t have a dedicated dehydrator, you may be able to simulate the results using a convection oven which can be run at lower temperatures.
