Apple Cider Vinegar in Your Kitchen and Health Routine

Apple cider vinegar has earned a permanent place in kitchens far beyond its role as a salad dressing ingredient. Its sharp depth improves braised vegetables, quick pickles, and marinades — and its uses extend well beyond cooking.

Apple cider vinegar is made by fermenting apple juice in two stages. First, yeast converts the sugars to alcohol. Then bacteria convert the alcohol to acetic acid, which gives all vinegars their sour character. The "with the mother" variety — which contains strands of bacteria and proteins from the fermentation process — has become the preferred form for health uses, though most culinary applications work equally well with standard filtered apple cider vinegar.

In the kitchen

The most versatile use of apple cider vinegar in cooking is as a finishing acid. Adding a small amount — one or two teaspoons — to braised dishes, soups, or bean stews just before serving brightens the flavour in the same way a squeeze of lemon does, but with a slightly more complex, fruity depth. This is particularly useful in dishes that have been cooking for a long time and have lost some of their early brightness.

Quick pickles are another reliable application. Combine one part apple cider vinegar with one part water, a teaspoon of salt, and a teaspoon of sugar, then pour over thinly sliced cucumbers, red onion, or radishes. Leave for 30 minutes at room temperature or overnight in the fridge. The result keeps well for several days and pairs with almost any savoury meal.

In baking, apple cider vinegar reacts with baking soda to produce carbon dioxide, which adds lift to quick breads and pancakes. Replacing buttermilk with a mixture of regular milk and a tablespoon of apple cider vinegar is a reliable substitute that produces comparable results.

As a salad dressing

A simple vinaigrette using apple cider vinegar is worth having as a consistent formula. Combine two tablespoons of apple cider vinegar with one teaspoon of Dijon mustard, half a teaspoon of honey, and six tablespoons of good olive oil. Shake or whisk until emulsified. The mustard acts as an emulsifier and holds the dressing together well. Season with salt and pepper. This keeps in the fridge for up to a week.

Health uses and what the evidence shows

Apple cider vinegar has a long list of claimed health benefits, and the evidence varies significantly depending on the claim. The most consistently supported use is in blood sugar management: several small studies have found that consuming vinegar with or before a carbohydrate-containing meal modestly reduces the post-meal rise in blood glucose. A 2019 review in the Journal of Evidence-Based Integrative Medicine summarised the available research and found the effect real but modest. This is potentially useful as part of a broader dietary approach, but not a replacement for medical management of blood sugar conditions.

Claims around weight loss, cholesterol, and detoxification are less well supported. The existing studies are often small, short, and funded by interested parties. This doesn't mean the effects don't exist, but it does mean caution is warranted before treating apple cider vinegar as a cure-all.

Safe use

Apple cider vinegar should always be diluted before consuming — the acidity can damage tooth enamel and irritate the oesophagus if taken straight. Dilute one to two tablespoons in a large glass of water if drinking it. Do not apply undiluted to skin — while it appears in many DIY skincare recipes, its acidity can cause irritation or chemical burns, particularly on sensitive skin.

People with gastroparesis, acid reflux, or who take medications that affect potassium levels should consult a doctor before incorporating apple cider vinegar as a regular health supplement.
