Baking Soda vs Baking Powder: Pakoras, Naan and the Acidity Risk
A quarter teaspoon. That’s the whole difference between a naan that rises soft and one that tastes soapy and turns a strange yellow. In the baking soda vs baking powder confusion, remember that meetha soda and baking powder look identical in the jar but aren’t interchangeable, and one of them is also misused as a stomach remedy.
In brief
- Meetha soda: pure sodium bicarbonate; needs an acid (dahi, lemon, imli) to work
- Baking powder: soda plus a dry acid; works with water and heat
- Strength: soda is roughly 3 to 4 times stronger
- Pakoras: a small pinch of soda per cup of besan, or none
- Not a daily antacid, especially with BP, kidney disease or pregnancy
Baking soda vs baking powder: what’s the difference
Meetha soda, khane ka soda, cooking soda, bicarbonate of soda: all the same thing. When it meets something acidic and moisture, it releases carbon dioxide gas, and those bubbles lift the batter. On its own with no acid, it doesn’t rise much and leaves a bitter, soapy taste and a yellowish colour.
Baking powder is soda already mixed with a powdered acid and a little starch to keep it dry. Most packets are “double acting”: a first set of bubbles when wet, a second burst in the heat of the oven or tawa. You can use it in recipes without any dahi or lemon.
Two quick freshness checks, because both lose power in humid kitchens:
- Soda: add 1/4 teaspoon to 2 tablespoons vinegar or lemon juice. Strong fizzing straight away means it’s good.
- Baking powder: add 1 teaspoon to 1/4 cup hot water. Lively bubbles mean good; lazy bubbles mean replace it.
Rule of thumb for swaps: 1 teaspoon baking powder ≈ 1/4 teaspoon soda plus an acid (like 1/2 cup dahi or 1 teaspoon lemon juice in the recipe). Going the other way, 1/4 teaspoon soda ≈ about 1 teaspoon baking powder, though swaps rarely come out identical, so try a small batch first.
Don’t confuse either with washing soda (sodium carbonate), sold for laundry and drains. It’s much harsher, it isn’t food, and it can burn the mouth and gut, so keep it in a separate cupboard, never in the kitchen spice shelf. Also, “Eno” style fruit salts are a mix of soda and citric acid; they’re a pharmacy product, not a baking ingredient, even though some dhokla recipes use them. The acid half of that mix is the same tatri in your cupboard.
How much in pakoras
Honestly, pakoras don’t need soda. Thick batter, hot oil and a little rice flour make them crisp. Soda makes them puffier but they absorb more oil and go soft faster. If you want it:
- For 1 cup (about 100 g) besan, use a pinch, about 1/8 teaspoon meetha soda. Never more than 1/4 teaspoon.
- Add it at the very end, just before frying, not an hour earlier. The gas escapes as the batter sits.
- Alternatively, stir in 1 teaspoon hot oil from the karahi into the batter. Many cooks do this instead of soda for a lighter bite.
- Fry at 170 to 175 °C.
Full batter ratios are in our besan cooking guide, and oil reuse is in the cooking oil guide.
How much in naan (tawa or oven)
Makes 6 naan. This uses both, because dahi gives the soda its acid and the powder gives an extra lift.
- In a bowl mix 2 cups (about 250 g) maida, 1 teaspoon baking powder, 1/4 teaspoon meetha soda, 1 teaspoon sugar and 3/4 teaspoon salt.
- Add 1/2 cup dahi (at room temperature) and 2 tablespoons oil. Mix into crumbs.
- Add about 1/3 cup warm milk or water gradually, kneading into a soft, slightly sticky dough for 5 minutes.
- Cover and rest 2 hours in a warm place. With no yeast, this rest is when the flour relaxes and the dahi works.
- Divide into 6 balls, roll into ovals about 5 mm thick, sprinkle kalonji and press in.
- Cook on a very hot cast iron tawa until bubbles appear, flip, then cook the top directly over a flame with tongs, or bake at 240 °C for 6 to 8 minutes. Brush with butter.
Soapy taste or yellow spots in the naan mean too much soda or not enough dahi to balance it.
Soda in chana and daal soaking
A pinch of soda softens tough kabuli chana, lobia or old rajma much faster, which is why cholay walay use it. It works by making the water alkaline, which breaks down the skins.
- For 1 cup dry chana, soak in 4 cups water with 1/4 teaspoon meetha soda for 8 to 10 hours.
- Drain and rinse well. Cook in fresh water, not the soaking water.
- Pressure cook 5 to 6 whistles, or simmer 1 to 1 1/2 hours.
The trade-off: alkaline cooking destroys some of the B vitamins (particularly thiamine) in pulses, and too much soda turns chana mushy and soapy. Better options first: buy fresher chana, soak longer, or add a teaspoon of salt to the soak. Keep soda for really old stock.
Soda was a newer addition to the desi kitchen, arriving with bakeries and colonial trade, but it spread fast: into khameeri roti shortcuts, into pakoras, and into the old household habit of “a pinch of soda in water” after an oily dawat. Hakeems relied more on saunf, ajwain and hing for heaviness after meals, and some older families still prefer those to soda.
The “soda for acidity” habit: why it’s risky
Sodium bicarbonate does neutralise stomach acid, and it’s an ingredient in some pharmacy antacids. That’s why a little in water feels like it works. The trouble is using it at home, repeatedly, with guessed amounts.
Half a teaspoon of baking soda carries a lot of sodium, more than many people should have in one go. Taking it often or in large amounts can upset the body’s acid-salt balance, cause fluid retention and swelling, and raise blood pressure. It is not something to repeat through the day or take every evening. Do not use soda as an acidity remedy if you have kidney disease, heart failure, high blood pressure or swelling in the legs, are pregnant or breastfeeding, or are on a low-salt diet. Never give it to children. Don’t take it on a very full stomach after a large meal; the gas it releases can be dangerous, and rare stomach injury has been reported. It also interferes with how some medicines are absorbed, so check with a pharmacist if you take regular tablets. If you need something for heartburn more than occasionally, ask your doctor or pharmacist rather than relying on soda, because frequent acidity deserves a proper look. Get urgent help for chest pain (it can be the heart, not acidity), black or bloody stool, vomiting blood, or trouble swallowing. Keep the box sealed and out of children’s reach.

Can I use baking soda instead of baking powder?
Only if the recipe has an acid like dahi or lemon, and use about a quarter of the amount.
Why does my naan taste soapy?
Too much meetha soda, or not enough dahi to react with it.
Is soda in water safe for acidity?
Not as a regular habit. It carries a lot of sodium and is unsuitable for people with high BP, kidney or heart problems, in pregnancy, and for children.
Is soda safe in pregnancy in food?
The small pinch used in cooking is fine. Taking it as a drink for acidity isn’t advised; ask your doctor for a pregnancy-safe option.
Does soda destroy nutrients in chana?
It reduces some B vitamins. Use the smallest pinch, rinse, and cook in fresh water.
How long does baking powder last?
Usually 6 months to a year once opened, less in humid kitchens. Do the hot water fizz test.
