This Thrifty Trick Saves My Shriveled Produce, Every Time

I have very little self-control at a good farmers market. 

You know that scene in, like, every episode of MasterChef where the contestants sprint into a comically oversized cold pantry, stuffed to the gills with 80 square feet of eggplants, more tomato varieties than you knew existed, and a crate of limes heftier than a six-year-old? The one that looks like this?

I produce-shop like I’m trying to stock that pantry. Safe to say, it’s a race against time to use up all of my vegetables and fruit. 

Shop the Story

That’s why it was such a game-changer for me when I stumbled upon a technique from Mads Refslund and Tama Matsuoka Wong to turn limp, fridge-shriveled carrots into DIY raisins, in their cookbook Scraps, Wilt & Weeds: Turning Wasted Food Into Plenty.

The basic idea is as follows: Chop up as many "last-legs" carrots as you have on hand, send them into a quick blanch to soften and add sweetness, and then use your oven at a very low temperature (or a dehydrator if you’re fancy!) to draw out moisture over a several-hour period.

Good news for me (and for my ever-wilting hoarder’s nest of seasonal produce): It doesn’t just work with carrots. You can use variations on this method to make “raisins” out of any hard-fleshed fruit or vegetable, and with a riffable flavor infusion during the blanch step, the resulting permutations are endless.

THE IMPORTANT STUFF

Repeat after me: There’s no wrong way to raisin. Just make sure to hit on a few key steps—chop to size, blanch thoughtfully, and bake ’til you’re happy with the texture:

Chop: The first thing you’ll want to do is cut up your wilting veggies or fruit into little bite-size pieces, which will become the raisins. The two important considerations here are size and uniformity. I’ve found that the ideal piece-size for this technique, in terms of expediting oven time and still retaining a chewy center, is roughly 1/2-inch by 1/2-inch. If you’re using something like cherries, no need to fuss over shape—just halve them and remove the pits. Most importantly, you'll want to get your pieces of fruit or vegetable to be relatively consistent in size so they’ll dehydrate at the same rate.

Blanch: Next, before you stick them in the oven, give your produce pieces a quick dip in a pot of boiling liquid. Mads and Tama recommend a blanching liquid that’s equal parts sugar and water (1 1/2 cups each). My go-to mixture incorporates apple cider vinegar and maple syrup, with a ratio of 3 cups water to 1 1/2 cups apple cider vinegar to 1 cup maple syrup. This is a great spot to get creative with different vinegars, spices, and sweeteners. Blanch until you can just pierce a fork through your fruit or vegetable pieces, between 4 and 10 minutes depending on what you’re using and how wilted it was to begin with. The goal of this step is primarily to soften the centers, which makes the dehydrating process quicker and gives the resulting raisins a better texture. It also helps to preserve color.

Bake: Remove your pieces from the blanching liquid with a slotted spoon, and place them onto a parchment paper-lined baking tray. Spread them out so they’re not touching one another. Stick the tray into the oven at 175° F, and start checking on your raisins for doneness around the 6-hour mark. Depending on what you’re using and your desired level of chewiness, the process could take anywhere from 6 to 10 hours. In their carrot raisins recipe, Mads and Tama recommend dehydrating the pieces until there’s no moisture left at all (which facilitates a super long shelf-life), and rehydrating them in reserved blanching liquid as needed. But I prefer to take mine out when the centers are still chewy and plump, like raisins you’d buy at the store. (They should last about three weeks this way.)

ALL THE WAYS TO RAISIN

Once you’ve got the basic steps down, the possibilities are infinite. The most promising options I’ve come across include:

  • On the fruit side: Pears, plums, apricots, cherries, apples, rhubarb, figs (sans skin), and of course, grapes.
  • On the veggie side: Carrots, beets, yams, radishes, and most other root vegetables.

SO YOU’VE GOT A MILLION RAISINS. NOW WHAT?

“One of the first times I was really intrigued by these raisins was when I ate at ACME, where Mads cooked,” says Tama. “He used them on a whole bunch of things.”

Tama recalls in particular a dessert Mads used to serve, which was beet raisins sprinkled over a cloud of yogurt and rye crumbles, with pickled cherries. (I had to pause to take a few deep breaths after I heard that—and had dreams about it for days.)

Less intimidating but equally delicious ways to use your new raisins include:

Can't help wondering: What are the economics of keeping on the oven at low temp for 6 hours?
To hasten drying in the oven, try keeping the door slightly ajar with a wooden spoon handle or similar.

This is a great article and I’m going to try this out to see how it comes out! Has anyone tried this with eggplant or peppers or zucchini or squash?
 
Michelle S. August 17, 2018
With cherry raisins underway, I can report that so far a 175-degree oven isn't raising the room temperature....

Is the sugar in the blanching liquid a requirement?
 
Ella Q. August 17, 2018
No, it's not a requirement--but including a sweetener adds to the flavor of the end product.

Such a great tip! Now I know what to do with those sad beets in my fridge.

This sounds like a really great idea! Only.... it’s freaking august in new york city so turning my oven on- much less for an extended period of time- just isn’t happening. I bookmarked this to try in the fall/winter since i love beets and carrots.
When my veggies are wilting they generally get added to a big stir fry in the summer, or shredded for slaw if they’re ok raw. In the winter i am constantly making soups and stews so they end up in one. I have a container in my freezer labeled as “black bean and random veggie peanut butter stew” :))

A summer stir fry sounds like a great way to use wilting produce--thanks for sharing!

Is there significant loss of vitamins and nutrients when you dehydrate, in essence cook, produce this way? Fiber and minerals, theoretically, shouldn't be affected, but what about vitamins? I'm curious.
 
Ella Q. August 16, 2018
Hi HalfPint,

That's a great question, I'm curious too! According to this NYT piece, dehydrating/drying fruit does result in a loss of some heat-sensitive vitamins and nutrients, like vitamin C:

The question might be a bit moot in this case since the produce is already compromised in terms of peak nutritional quality - love the idea of making veggie raisins!
 
Ella Q. August 16, 2018
Thanks Nancy! I'd love to hear how it goes, if you try it out.
