What Is Tatari (Cream of Tartar)?

Cream of tartar is the common name for Potassium Bitartrate (chemical formula: KHC₄H₄O₆ — potassium hydrogen tartrate). It is a byproduct of winemaking: as grape juice ferments into wine, tartaric acid — naturally present in grapes — crystallises out and forms a crust (called "tartar") on the inside of the fermentation vessels. This tartar is harvested, purified, and milled into the fine white powder sold as cream of tartar.

Chemically, cream of tartar is an acidic potassium salt with a mildly tart, slightly acidic taste. When dissolved in water, it behaves as a mild acid. When combined with baking soda (sodium bicarbonate), it reacts to release carbon dioxide gas — the principle behind its primary culinary use as a leavening component. Despite the name "cream," it contains no dairy and is a completely dry crystalline powder.

In the Indian traditional medical context, Tatari is found in Unani medicine (where it is known as Tartir or Hazar-e-Mash in some texts) as a mildly detoxifying and digestive substance. In folk and household tradition across India, it has been used as a natural cleaning agent, a digestive support, and a source of dietary potassium.

How to Identify Genuine Cream of Tartar

• Appearance: Pure cream of tartar is a fine to moderately fine white crystalline powder — similar in appearance to baking powder or fine table salt. It should be uniformly white without grey, yellow or brown tinge, which would suggest impurities or contamination.
• Taste: Cream of tartar has a distinctly tart, acidic taste — similar to the sourness of tamarind water or diluted lemon juice, but dry and without fruitiness. This tartness is its most recognisable organoleptic property. Baking powder (a common point of confusion) tastes bitter-alkaline, not sour-acidic — this is an easy way to distinguish them.
• Reaction test: Place ½ teaspoon of cream of tartar in a glass of water and add ½ teaspoon of baking soda. Genuine cream of tartar will immediately fizz and bubble vigorously (CO₂ release from the acid-base reaction). This simple test confirms both the identity and reactivity of your cream of tartar.
• Solubility: Cream of tartar dissolves partially in cold water but more readily in hot water. It does not dissolve instantly in cold water (unlike table salt or sugar) — some fine crystals may remain. This limited cold-water solubility is characteristic and normal.
• Adulteration: Cream of tartar is sometimes adulterated with starch, baking powder, or citric acid powder. The reaction test with baking soda is the most reliable quality check at home.

Traditional and Practical Uses

Cream of tartar (Tatari) has several well-established traditional and practical uses:

• Baking — stabilising egg whites: Cream of tartar is most famous in the kitchen for its ability to stabilise whipped egg whites and meringue. Adding ⅛ teaspoon per egg white strengthens the foam structure, prevents weeping (syneresis), and allows meringue to hold its shape for longer. This is its single most important culinary function.
• Baking — leavening agent: Cream of tartar is the acid component in homemade baking powder (1 part baking soda + 2 parts cream of tartar = DIY baking powder). This combination is used to leaven cakes, pancakes, biscuits, and quick breads. Using cream of tartar and baking soda separately gives the baker direct control over leavening strength.
• Preventing sugar crystallisation: A small amount of cream of tartar (⅛–¼ teaspoon per cup of sugar) added to cooked sugar syrups, caramel, toffee or fondant prevents the sugar from re-crystallising (graining). This is a standard professional baking technique for smooth, glossy confections.
• Keeping vegetables bright: Adding a pinch of cream of tartar to the boiling water when cooking vegetables helps maintain their bright colour by keeping the cooking water slightly acidic.
• Digestive and alkalizing support (traditional): In Unani medicine and traditional household use, small amounts of Tatari dissolved in warm water have been used as a mild digestive support. Potassium bitartrate's mild alkalizing effect on urine (despite being an acidic salt in solution, it increases urinary alkalinity by providing dietary potassium and promoting bicarbonate retention) has led to its traditional use in folk approaches to digestive and urinary comfort. These are traditional uses — they are not medical treatments.
• Dietary potassium source: Cream of tartar is an unusually rich source of potassium. One teaspoon (approximately 3g) provides approximately 495mg of potassium — roughly 10% of the adult daily requirement. Potassium is an essential electrolyte that supports heart function, muscle contraction, blood pressure balance, and nerve signalling. Traditional formulations for electrolyte support sometimes include small amounts of cream of tartar.
• Household cleaning agent: A paste of cream of tartar with a small amount of water (or hydrogen peroxide for tougher stains) makes an effective, non-toxic cleaner for stainless steel, aluminium cookware, tile grout, and porcelain. Its mild acidity dissolves mineral deposits, rust stains, and discolouration without harsh chemicals.

These are traditional, nutritional and practical uses. Cream of tartar is a food-grade ingredient — it does not treat, cure or prevent any disease. Consult a doctor for any health condition.

How to Use Tatari (Cream of Tartar)

• In baking (meringue, pavlova, angel cake): Add ⅛ teaspoon (pinch) per egg white before whipping. This amount is sufficient to stabilise the foam without affecting flavour.
• As a baking powder substitute: Mix 1 part baking soda with 2 parts cream of tartar. Use the same amount as regular baking powder called for in the recipe. For example, 1 teaspoon of commercial baking powder = ¼ teaspoon baking soda + ½ teaspoon cream of tartar.
• For sugar syrup (preventing crystallisation): Add ⅛ teaspoon per cup of sugar to candy syrups, caramel or fondant while cooking.
• Electrolyte drink (traditional): Dissolve ½ teaspoon of cream of tartar in 500ml of water with a squeeze of lemon and a small pinch of salt. This traditional preparation provides potassium and mild alkalizing support. Not a substitute for medical electrolyte preparations in cases of illness.
• Cleaning paste: Mix cream of tartar with a small amount of water or white vinegar to form a paste. Apply to stainless steel, aluminium, porcelain or tile, let sit for 5 minutes, then scrub and rinse.
• Food-grade safety note: Cream of tartar used for cooking, baking and food preparation is food-grade (E336 in the EU food additive classification). Use food-grade Tatari for any internal purpose. Industrial-grade tartrate products are not suitable for consumption.

Safety

Cream of tartar is a food-grade ingredient with a long history of safe use in cooking and baking. However, several cautions apply:

• Kidney disease: Cream of tartar is very high in potassium (approximately 495mg per teaspoon). People with kidney disease or on potassium-restricted diets must avoid taking cream of tartar as a supplement, as excess potassium can be dangerous. Consult your doctor if you have kidney disease or take medicines that affect potassium levels (such as ACE inhibitors, potassium-sparing diuretics, or ARBs).
• High blood pressure medicines: Many blood pressure medicines affect potassium balance. Consult your doctor before taking cream of tartar regularly as a potassium supplement alongside any blood pressure medication.
• Do not use in large amounts: Cream of tartar in large amounts (more than 1–2 teaspoons per day as a supplement) may cause hyperkalemia (excess potassium) in susceptible individuals — a serious condition that affects heart rhythm. Use only in the small culinary amounts typical for baking and cooking unless advised otherwise by a healthcare professional.
• Children: Safe in normal culinary amounts. Do not give supplemental doses to children without medical guidance.
• Pregnancy: Safe in food amounts as a cooking ingredient. Large supplemental amounts should be avoided without medical advice.
• See a doctor if: You experience unusual heart palpitations, muscle weakness, tingling, or numbness after consuming significant amounts of cream of tartar. These may be signs of electrolyte imbalance — stop use and consult your doctor.

Frequently Asked Questions

What is cream of tartar good for?

Cream of tartar has three main types of uses: (1) In baking — stabilising whipped egg whites for meringue and pavlova, acting as the acid component in baking powder, and preventing sugar crystallisation in confectionery; (2) As a potassium source — it is one of the most concentrated natural food sources of potassium, useful in electrolyte drinks; and (3) As a cleaning agent — a mild, non-toxic acid cleaner for stainless steel, aluminium and porcelain. Traditionally it has also been used in small amounts as a digestive and alkalizing support.

Are baking soda and cream of tartar the same?

No — they are chemically opposite. Baking soda (sodium bicarbonate, NaHCO₃) is an alkaline compound; cream of tartar (potassium bitartrate, KHC₄H₄O₆) is an acidic compound. When mixed together in the correct ratio (1 part baking soda to 2 parts cream of tartar), they react to form CO₂ gas — producing the same leavening effect as commercial baking powder. They are frequently used together, but they are not interchangeable individually.

What is a good substitute for cream of tartar?

The best substitutes depend on the use. For stabilising egg whites: a few drops of lemon juice or white vinegar (½ teaspoon per egg white) works almost as well. For leavening (as part of baking powder substitute): use commercial baking powder (1 teaspoon replaces ¼ teaspoon baking soda + ½ teaspoon cream of tartar). For preventing sugar crystallisation: a few drops of lemon juice or white vinegar can be used. For potassium content: no simple food substitute provides as concentrated a source — whole foods like bananas, sweet potato and spinach are general dietary potassium sources.

Is cream of tartar an electrolyte?

Cream of tartar is a very rich source of dietary potassium — one of the five key electrolytes (alongside sodium, magnesium, calcium, and chloride). One teaspoon provides approximately 495mg of potassium. Dissolved in water with a pinch of salt and lemon juice, cream of tartar can serve as a simple, traditional potassium-rich electrolyte drink. It is not a complete electrolyte replacement and should not replace medical oral rehydration solutions in cases of illness-related dehydration.

Which is better for cleaning — vinegar or cream of tartar?

Both are mildly acidic non-toxic cleaners, but they work best in different situations. Vinegar (acetic acid solution) is excellent for dissolving calcium carbonate deposits (limescale) on taps, kettles, and glass. Cream of tartar (potassium bitartrate) is gentler and forms a paste more easily, making it better for polishing and removing light discolouration from stainless steel, aluminium cookware, and porcelain. Combining cream of tartar with a small amount of white vinegar creates an effective paste for stubborn stains that neither would handle as well alone.

What happens if I use too much cream of tartar in baking?

Using too much cream of tartar in baking has several effects depending on the quantity and application. In meringue or whipped egg whites: excess cream of tartar can make the foam weep and become unstable, and may give a metallic or sour aftertaste. In baked goods (excess baking powder mixture): too much acid relative to baking soda can prevent full neutralisation, leaving a residual sour taste and potentially producing a dense, pale crumb instead of a light, risen result. In cooking: the usual small amounts used in culinary applications carry no significant health risk. As a rule, use cream of tartar in the small amounts typical of baking recipes — ⅛ to ½ teaspoon — and do not exceed these without a specific culinary reason.
