Spring Greens

We talk, endlessly it seems sometimes, about how to use vinegar.  Sometimes we give out recipes with obscure French names.  One of my favorite ways to use vinegar, however, is so simple that a recipe will not do.

Sweat a little onion in butter in a large pot for a few minutes, add a healthy splash of vinegar and a pinch of salt, turn up the heat to high, and then stuff fistfuls of greens into the pot before covering.  Uncover a few seconds later and stir it around good.  The vinegar has steamed the greens and given them flavor.  Eat immediately, as in the example below with gouda and hummus on toast.

Happy 2018 Everybody!

We're wasting no time making waves this year!  Check us out at Toli Moli, one of our newest retailers, as per this article from dcrefined.  We first started making vinegar in serious production while we were occupying the space now called Toli Moli (Honeycomb back then).  They have tons of our flavors!

Also check out this interview in The Town Dish - they're really thoughtful writers.  For all of our Philadelphia friends, come check us out at Winter Fare this Saturday, January 12!

Unabashed richness, on and off the table. Happy Thanksgiving!

We’ve been having fun cooking with our malt vinegar.  Since it tests at a higher acidity than our usual standard, but hints at sweetness through aroma, it stands up well to other strong flavors.  In this dish, we’ve dressed roasted acorn squash with a brown butter malt vinaigrette, sat it in a garlic-parmesan fonduta, and tossed a few pecans on top.


Brown Butter Vinaigrette

Makes a lot; lasts forever.

2 sticks butter

1/2 cup chopped leek

12 big sage leaves

1/4 cup Keepwell malt vinegar

1 tbsp maple syrup

Salt and pepper to taste

Melt the butter and continue to cook over medium heat in a 2 quart saucepan.  When it starts to foam and begin to brown, whisk it as it cooks, letting it deepen in color until it smells nutty.  Don’t worry if you get close to burning, because you can toss the leeks in (gently) as soon as you’ve achieved the color you desire. They’ll drop the temperature back down immediately.

Once the leeks are cooking, chiffonade the sage and drop that in the pan.  Let it cook, about 5 minutes over medium heat – the leeks should be contentedly bubbling away in the fat.  Once you see the leeks taking on color of their own, stir in the vinegar and maple, then salt and pepper. 

Now taste the vinaigrette – if it’s too sharp, let it simmer again for a minute or two,, which ought to dull the acidity a bit.  Nothing wrong with adding a pinch more maple.   Reserve warm to drizzle over your roasted squash.

Garlic-parmesan Fonduta


8 cloves of garlic, peeled

1 stick of butter

1/2 cup milk

1/2 cup grated hard cheese

1/2 tsp nutmeg

salt to taste

Cook the garlic in the butter in a very small saucepan over the very low heat.  The aim is to get the garlic completely soft – don’t be tempted to chop it, as the flavor of the whole garlic is much gentler.   Once you can squish the garlic with the back of a spoon, add the milk and cheese.  Let it all get warm again over the low flame, and puree in a blender.  Pour it back into the pan, salt to taste, and reserve warm until it’s time to eat.


Michael Harlan Turkell's book, ACID TRIP, out since August and available here, has no index.  This is purposeful; you're meant to follow the author's travels through the world, stumbling on methods and techniques for the creation and use of vinegar along the way.  The 'Dressings & Sauces' portion of the table of contents leads you to, in sequence, the following pages: 115, 180, 41, 34, 236.

This conceit in another person's hands might get frustrating, but the reader is lucky that Turkell is an engaging storyteller, so you don't mind that the chronogeological basis for the book's organization presents recipes, history, technical how-to, and serious foodie namedropping all together in the same course.  It doesn't careen so much as wander, and it's a much better format for a cookbook than the dry old vignette/recipe alternation, as long as the author is interesting and personable.

Listen to Turkell yourself talk about vinegar here at this Bon Appetit podcast, before you go cop a copy.  Do it for National Vinegar Day on November 1st!

Hot and Sour Soup

Springtime is here, not just by the mercury but the produce aisle as well now.  

Yesterday we bought bok choy raab, spring onions, cilantro, and hakurei turnips.  What does that add up to?  If you said hot and sour soup, then you love vinegar as much as I do.  It might not be so heavily associated with light springtime brodos, but hot and sour soup has got it all: a bracing broth, the versatility to accept what the season offers, and a 0-60 of an hour, max.

Here's how it goes in the Keepwell household.  Pick some mushroom stems off of their caps, rough chop a small onion and a couple stalks of celery, and tear a tiny nub off of some ginger root.  Give that pile a quick go-round in the food processor, and sweat the resulting mash in a couple of tablespoons of sesame oil, in a decent-size saucepan.  Once you've worn off the raw edge, the vegetables will stop sweating and start sticking, at which point you can drop 1-2 quarts of water in.  Bring it quickly to a simmer and let it go for about 15 minutes.

Which is the perfect amount of time to get the other half of the recipe going!  Prepare some vegetables, dice up a little tofu, get some nice garnishes together.  You'll saute your mushrooms, spring onions, and any hard vegetables in a little more sesame oil. A quick cooking little cut like pork skirt goes in nicely right here as well - bonus points if you rub that sucker beforehand with gochujang or something similar that will really caramelize in the pan.  

By the time you really get cooking, your broth should have some flavor and be ready for final seasoning.  Then you put the two together and bring it up to a simmer.  Toss in anything green like asparagus in right before you serve.  

HOT AND SOUR SOUP, 4/29/2017

Double fistful of mushrooms (cremini in the picture, whatever you prefer)

1 bunch spring onions

1 bunch hakurei turnips

2 tbsp sesame oil

1 quart mushroom broth, as described above

dash Keepwell Vinegar brand black garlic vinegar

dash Keepwell Vinegar brand Carolina Gold rice vinegar

1 tbsp of your favorite red hot sauce (we use gochujang because we make dope gochujang)

dash soy sauce

1 bunch bok choy raab

4 oz fresh soft tofu, cut up

1 bunch cilantro

Pickled garlic scapes

Chop the white part of the spring onion, the hakurei turnips, and the mushrooms into bite-size pieces, and saute them in the sesame oil over medium heat.  They'll only take a minute to develop some color.  Remember they'll simmer in the broth for a second, so don't overcook them here.  

Season your mushroom broth with the vinegars, hot sauce, and soy sauce until it's lively enough for you, then drop it into a saucepan with your sauteed vegetables and the tofu.  Bring it all up to a simmer together, taste and adjust as needed.  Add the bok choy raab and plate it more or less immediately - it will continue to cook in the hot broth.  

Garnish with a fat handful of cilantro, hastily torn apart, and some pickled garlic scapes.  If your pickle brine from the scapes has any sugar in it, consider leaving it on the table for any guests who want a pinch of sweetness.

Aronia Berry Vinegar

Aronia berries are awesome.  I avoided them for a while because they'd been branded a 'superfood', but I was convinced by a glass of hard cider from Distillery Lane, fermented with aronia berries present.  The unpleasant astringency of the raw fruit becomes a mellow tannic drying after fermentation.  

So when Dylan (of Dylan's Oyster Cellar, where they're working on some fabulous Keepwell Vinegar mignonettes)  mentioned that his cousin at Chester River Aronia was trying to move some serious weight in berries, we knew what to do.  We are currently the proud owners of hundreds of gallons of tart, tannic, berry vinegar.  

The resemblance in mouthfeel to some grape wines is remarkable.  As we were casting about for dinner ideas the other night, I thought of beurre rouge, which uses both red wine and red wine vinegar.  The aronia berry vinegar has qualities of both, so we substituted it 100% for all liquid ingredients.  Delicious!

Aronia Berry Beurre Rouge

1 larger shallot

1 sprig tarragon

1 bay leaf

1 cup Aronia Berry Vinegar

1 stick of cold butter in 1/2" dice

Mince the shallot up nice and small.  Bring the vinegar up to a boil with the shallot, tarragon, and bay leaf. Reduce at a simmer until it's jammy and almost dry; there should only be a few tablespoons left.  Turn the heat off and whisk the butter in, a few dice at a time.  It should emulsify readily.

Serve with scallops, duck, beef, or just a nice pile of potatoes, mushrooms, and onions.

Turns out, centuries of Japanese tradition had something to contribute to the conversation

Sometimes we get pulled back to earth.

We have been refining a method for converting grains into vinegar for a few years now.  It's informed a little by the miso-making process, has some notes cribbed from beer brewing, and then sloshes into our regular routine for finishing and aging all of our vinegars.  It's either a synthesis or a corruption of traditions, depending on where you stand. I will say that it does a good job pulling the character of rye or toasted barley through a long fermentation.

It was around our fourth or fifth time ruining expensive Carolina Gold rice that we decided that our method simply did not work for rice.  We were surely making vinegar, but losing all of the flavor of the grain.

Sarah decided to follow the technical instructions for the production of sake, following them strictly enough that we purchased the special strains of yeast, rather than using our usual collection of raw natives.  

The resulting rice wine vinegars, first of Carolina Gold and then from some freshly polished Koshihikari from Blue Moon Acres, are exceptionally aromatic, sweet-smelling, wistful and elusive. We found what we'd been missing.  Addition by subtraction of arrogance. In its place, pride can grow. 

Vinegar Tasting Party

Come down to Little Red Fox on Saturday December 10 to taste some vinegars with the real deal makers, Sarah Conezio and Isaiah Billington (that's us).  We'll have some interesting flavors for you to try, bottles for sale, shoot, we'll make some (vinegary) snacks.  

Matt Carr and the team at Little Red Fox have been some of our earliest supporters at Keepwell Vinegar - if you're not familiar with the shop already, they have good food and coffee, Chef Bobby uses our ferments in creative ways, there's some cool locally-sourced merch and produce, and they make a heck of a croissant.

Origins: A Speaker Series: The Episode with Keepwell Vinegar In It

Origins: A Speaker Series is an awesome show taped for the Heritage Radio Network at Artifact Coffee in Baltimore.  The show has covered Pennsylvania Dutch food ethnography with William Woys Weaver (first lesson, 'Penn Dutch' is not a strict synonym with 'Amish'), growing healthy grains and baking with freshly milled flour (here they had the farmer and the baker representing - both personal heroes of ours), and a bunch of other topics anybody who likes to think about what they eat will enjoy.

And they had us on!  Listen to the episode we appeared in here alongside some much more well-spoken people.  We got some really interesting question before we had to wrap up, although there's one that I answered poorly - someone asked which apples we favor for our single varietal apple cider vinegars.  We always get better at this one, but I've added an emphatic favorite since the taping: the York Imperial, an apple that first sprang from York, grows well there, and was once the most widely grown apple in the area surrounding for its qualities as a cider and sauce apple.  The flavor is sweet enough, sharp enough, but also really pleasantly woody and tannic.  Making hard cider to drink is almost never done with a single varietal, there's just too much balancing to be done.  I'll bet if one apple could do it though, it'd be the York Imperial.

Of course, we have hundreds of gallons of that going thanks to the efforts of Ben Wenk, who's bent over backwards to press varietals at their peak for us using apples from his family's farm, Three Springs Fruit Farm.  Indicentally, he spoke at the most recent Origins taping, all about orcharding.  Look out for audio release soon!
