Hi I have recently really been getting into cooking however the girl I am dating has allergic reactions to vinegar, which is in a lot of sauces and stuff.

Looking for possible substitutes that might work when recipes call for this, currently use lemon juice but sometimes that tastes weird (For example I tried to make ketchup since she can't have kraft ketchup which she use to love, however lemon juice tasted quite horrible for my try at it).

Let me know what I should be using! thanks:)

  • Vinegar, alias acetic acid, is present almost everywhere. I don't believe your girlfriend is, per definition, allergic to vinegar. – Gyro Gearloose Apr 26 '16 at 19:49

    To distilled white vinegar (dilute acetic acid, as GyroGearloose mentions) or to white/red/etc. wine vinegar? – derobert Apr 26 '16 at 20:32

    @GyroGearloose an "allergy" to vinegar is different from an actual allergy, as the body's immune system isn't involved, but the symptoms can be very much the same. See michiganallergy.com/food_and_histamine.shtml – Jolenealaska Apr 26 '16 at 22:11

    Not posting as an answer as allergies are a weird thing, but try Formic Acid (best known from ant stings) as that's an acid that can be used in the kitchen (and has a chemical formula similar to but different from vinegar)... I use formic acid as it has no vinegary taste to clean coffee makers and will use it as a substitute if someone else misplaced the @#&$*{ vinegar bottle: just a few drops is enough but the GF might be allergic to it too, so try a 1% solution and if that works, go to 2, 3, ... Ping me @Fabby if that works. – Fabby Jul 8 '18 at 22:28
  • @Fabby Is this something you need to buy online? Still have yet to find a good substitute, but have not tried this one yet. – Lain Jul 9 '18 at 15:12

Citrus juice is probably the most widely available substitute. However, if you can get your hands on some Verjus (or Verjuice) you will be pleasantly surprised.

Verjus is the juice of pressed green grapes. It is similar to wine but the grapes haven't had a chance to ripen and there isn't any alcohol. It has a much more neutral flavor than lemon juice. It can be difficult to find though. I buy mine at a local vineyard. You may be able to find some online.

Citric acid powder or granules, as opposed to lemon juice. This will impart less undesired flavor than lemon juice, should be a better substitute. 1/4 teaspoon substitutes for 2 tablespoons of 5% vinegar, or 1 tablespoon lemon juice. I got mine from Amazon.

I have been allergic to vinegar for years, I cook frequently and have not found a substitute for most condiments because as a couple of you noted- citric acid usually tastes bad, and nothing tastes like vinegar.

A few tips:
Coleman’s mustard doesn’t have vinegar! Make your own hot sauce by boiling and pureeing habenaros (wear a mask). Make your own mayo with lemon juice. Homemade hollandaise is also vinegar free when lemon is used

    Hello, and welcome to Stack Exchange. While interesting, this doesn't answer the original question. – Daniel Griscom Jul 7 '18 at 18:51

    Actually, “there is no good substitute” is an answer - even if it’s not necessarily what the OP was hoping for. Whether it’s a correct answer is another issue, but it seems that others agree. – Stephie Jul 8 '18 at 13:52

Unfortunately there really isn't anything that tastes like vinegar except for vinegar, and the lemon juice you're trying is about as close as you're going to get.

It just comes down to chemistry. Most categories of edible compounds, like starch, protein, hydrocarbon lipids, etc. have a ton of different compounds in them, so if you have to avoid one you can often find another with very similar characteristics regarding flavor and how it reacts with other compounds when being cooked. These chemical similarities are what allow for good substitutions.

The problem is that vinegar comes from the much less human-friendly compound category of acids. The list of edible acids is incredibly short, and once you rule out the ones you either can't use (carbonic only exists in carbonated drinks) or wouldn't ever want to put in your mouth (butyric and lactic come from spoiled dairy products), you only have a handful of possibilities. The food acids you're left with at this point are:

  • oleic (olive oil)
  • palmitic (palm oil)
  • oxalic (tomato)
  • tartaric (tamarind)
  • citric (citrus obviously)
  • acetic (the vinegar you're trying to get away from)

The only thing on that list that even remotely shares vinegar's tanginess is citric acid, which is why lemon juice is the standard suggestion to use in a pinch if one is out of vinegar.

Your best bet would be to experiment with other citrus juices and see if perhaps using something other than lemon would help things taste better.

    I wonder how you came to your list, but it isn't very helpful. It lacks some of the most common edible acids (malic and lactic at least, maybe more), cites an unusual source for oxalic acid (tomato), lists oxalic as a good substitute for vinegar even though it is toxic and cannot be consumed at levels comparable to vinegar consumption, and suggests two fatty acids, which are chemically indeed an acid, but culinary completely unsuited as a vinegar substitute. – rumtscho Apr 27 '16 at 16:06

    @rumtscho My apologies, but I didn't imply that oxalic was a vinegar substitute, nor did I offer the fatty acids as substitution candidates. In fact I explicitly state that none of them are viable subs except for the citrus. That was my entire point; Vinegar's flavor comes from being an acid, so a substitute would have to be an acid. Most acids will kill you and the few that are safe to eat taste nothing alike and wouldn't react the same way if cooked, which is what the list illustrates. If you reread my answer, I think you'll see your comment is actually agreeing with and reiterating my point – Barkode Apr 27 '16 at 17:32

I find rhubarb juice home made is fabulous in oil and “ vinegar” salad dressing. I can’t eat vinegar or alcohol or citrus. Didn’t know about ascorbic acid.

Rhubarb juice rocks it and there is a lovely pink color
