Peanut Butter: How to Choose a Good Jar and Make It at Home
Turn the jar around before you look at the price: good peanut butter lists peanuts, and maybe salt, and nothing else. Here’s how to choose peanut butter in a Pakistani or Indian shop, why the oil on top is a good sign, how to make it at home from roasted mungphali, and the honest calorie, allergy and child-safety facts.
In brief
- Best label: “Peanuts” or “Roasted peanuts, salt”. That’s it.
- Skip if you can: added sugar, “hydrogenated vegetable oil”, palm oil and long lists of stabilisers.
- Calories: about 95 kcal per level tablespoon (16 g), with roughly 4 g protein.
- Oil on top: normal in natural peanut butter. Stir it back in.
- Toddlers: a thin smear only, never a spoonful.

How to choose peanut butter: reading the label
Three kinds of jar sit side by side on most shelves in Pakistan and India, and they look almost the same. They aren’t.
| Type | Usual ingredients | Verdict |
|---|---|---|
| Natural or “100% peanuts” | Peanuts, sometimes salt | The one to buy |
| Classic creamy or crunchy | Peanuts, sugar, hydrogenated or palm oil, salt, emulsifier | Fine now and then, more like a spread |
| “High protein” or flavoured | Peanuts plus whey or soy protein, sweetener, cocoa, jaggery or honey | Read carefully; often more sugar than you’d guess |
- Read the ingredients, not the front. They’re listed from most to least, and peanuts should make up the whole jar or close to it.
- Check sugar per 100 g. Peanuts carry a little natural sugar, so a plain jar shows a small number, usually under 10 g, while a figure of 15 g or more per 100 g means sugar was added somewhere along the line.
- Look for the oil. “Hydrogenated vegetable oil” or “vegetable fat” stops the jar separating, but partly hydrogenated oil can carry trans fat, the kind worth avoiding completely, so if the label says hydrogenated and doesn’t show “0 g trans fat”, put it back.
- Check sodium, date and seal. Salted jars vary. Buy the newest batch.
A cheaper jar that says “peanuts, salt” beats a fancy one full of sugar and palm oil. Our one-minute snack label guide uses the same method for biscuits and namkeen.
Why is my peanut butter separating? (It’s supposed to)
Natural peanut butter separates because nothing in the jar holds the oil in place, and peanut oil, being lighter than the ground nuts, rises and pools on top. Fewer additives. Not a fault.
- To mix: stir with a butter knife right to the bottom, then keep the jar in the fridge, where cold oil thickens and stays put.
- Don’t pour off the oil. What’s left turns dry, hard and crumbly.
Dry and hard? Either the oil was poured off or the jar is fridge-cold; leave it out for 15 minutes and stir.
How to make peanut butter at home
You need a strong mixer grinder or food processor, 300 g peanuts and patience. Makes about 1 cup.
- Sort the peanuts. Spread 300 g raw peanuts (about 2 cups) on a plate and throw away any that are shrivelled, discoloured, dusty or mouldy, because with aflatoxin in the picture (see below) this step matters more than any other.
- Roast. Dry roast in a heavy karahi on low heat for 8 to 10 minutes, stirring constantly, until golden and fragrant and the skins crack. In an oven, 160 °C for 12 to 15 minutes.
- Cool and skin. Cool for 10 minutes, rub in a cloth and blow the skins away (leaving some is fine).
- Grind in stages. Run the grinder 1 minute at a time, scraping the sides between rounds, and you’ll see crumbs, then a thick ball, then a smooth, runny paste as the oil releases, usually after 5 to 10 minutes in all; if the jar gets hot, rest the motor.
- Season if you like. Add a pinch of salt (about a quarter tsp). Skip sweetening it, or add 1 tsp gur powder for adults.
- Jar it. Spoon into a clean, completely dry glass jar and keep it in the fridge.
Never add water. It makes the paste seize and gives mould a place to grow. For crunchy, pulse a handful of roasted peanuts coarse and stir them in at the end.
Aflatoxin, rancid jars and how to store peanut butter
Peanuts stored damp and warm can grow a mould that makes aflatoxin, a poison that harms the liver over time, and roasting doesn’t reliably destroy it. That’s why sorting matters at home. It’s also why tested brands beat loose, unlabelled paste. Our mungphali guide on aflatoxin and allergy covers how to buy clean peanuts.
- Shop jars with stabilisers: a cool, dark cupboard is fine for a few months after opening.
- Natural and homemade jars: fridge after opening, especially in summer; use homemade within a few weeks.
- Always: a clean, dry spoon, since crumbs of roti or jam left in the jar invite mould.
Rancid peanut butter smells sharp, like old paint or crayons. Mould, a sour smell or a fizzy look means the whole jar goes, not just the top.
Peanut butter calories and nutrition, honestly
It’s sold as a protein food. It’s really a fat food with a useful amount of protein: per level tablespoon (16 g) you get about 95 kcal, around 4 g protein and 8 g fat, most of it the unsaturated kind. Roughly three quarters of its calories come from fat.
A heaped spoon can be double that.
- Protein: 2 level tablespoons give about 8 g protein for about 190 kcal, while one egg gives about 6 g for about 75 kcal. Helper, not main source.
- Heart and cholesterol: peanuts have no cholesterol and mostly unsaturated fat, so plain peanut butter can fit a heart-friendly diet in sensible amounts; sugary, palm-oil jars fit less well.
- Diabetes: plain peanut butter barely raises blood sugar by itself, and spread thinly on wholewheat roti or toast, or paired with an apple, it slows the rise from the carbohydrate eaten with it. Jelly undoes that.
- Weight loss: it helps you feel full if you measure, but two heaped spoons “for protein” can add 300 kcal before you notice.
Peanut butter for weight gain
It’s one of the easiest ways to add calories without feeling stuffed. First, though: if you’re losing weight without trying, or can’t gain despite eating well, see a doctor before changing your diet. Thyroid problems, diabetes, TB, coeliac disease, infections, depression and eating disorders can all be behind it.
A realistic gain is about 0.25 to 0.5 kg a week, from eating roughly 300 to 500 kcal a day more than you burn. A tablespoon of peanut butter on your morning toast and another in a shake covers a good part of that. Pair it with simple strength work, like squats, push-ups against a wall or carrying water bottles up the stairs, so more of the gain goes to muscle.
Banana peanut butter shake (about 400 kcal)
Blend 250 ml full-fat milk, 1 medium banana, 1 level tbsp plain peanut butter and 2 tbsp oats until smooth. Drink it with breakfast or as an evening snack. More shake ideas are in our homemade weight gain shakes and laddoos.
Skip unlabelled “wazan barhane” powders and syrups, because some sold online or over the counter have been found to hide steroids or appetite drugs, while peanut butter, milk, eggs and daal do the job honestly. More in Desi Weight Gain.
Peanut butter for babies and kids: allergy and choking
Peanut allergy can be serious, and current advice for most babies is to introduce peanut early, once other solids have started at around 6 months, rather than wait. Babies with severe eczema or a known egg allergy should see their doctor first, because they’re more likely to react.
- Mix a quarter teaspoon of plain, unsalted, unsweetened peanut butter with 2 to 3 tsp warm water, breast milk or formula until runny, or stir it into a baby cereal.
- Offer it at home, in the morning, when the baby is well, and watch for 2 hours afterwards. Hives, swelling of lips or face, repeated vomiting, coughing or wheezing means stop and get medical help at once.
Toddlers? Spread thin. Never give a spoonful of thick peanut butter to a child under 4 or 5: it sticks to the roof of the mouth and can block the throat. Whole peanuts are a choking hazard under 5. No homemade peanut butter sweetened with honey for babies under 1.
Long before jars arrived, desi kitchens ground roasted mungphali on a sil batta with salt and green chilli into a chutney, or with gur into chikki and laddoos. Plain peanut butter is the same idea without the chilli or sugar, and a jar of it is a handy way to use peanuts in winter when they’re fresh and cheap.
Surprising facts about peanut butter
- Peanuts aren’t nuts. They’re legumes, like daal and beans, that ripen underground.
- Some “sugar-free” peanut butters contain xylitol, a sweetener that’s safe for people but poisonous to dogs. Check the label before sharing with a pet.
- Crunchy and smooth are nutritionally almost the same. Pick by taste.
You have a peanut allergy: avoid it completely, and read “may contain peanuts” warnings on other spreads too. Anyone with swelling of the tongue or throat, or trouble breathing, after eating peanut needs emergency care. Kidney disease: peanut butter carries potassium and phosphorus, so ask your renal dietitian how much fits. Diabetes on insulin or sulfonylureas: if you swap roti or rice for peanut butter, your sugar can drop too low (a hypo), so talk to your doctor before changing meals. Children under 5: thin smears only, no whole peanuts.

Peanut butter questions people ask
Is peanut butter good for you?
Plain peanut butter is a nutritious food in small amounts, giving unsaturated fat, some protein, fibre, vitamin E and magnesium in every spoon. The trouble is portion size and added sugar or palm oil, not the peanuts.
Can diabetics eat peanut butter?
Yes, plain peanut butter is a reasonable choice for diabetics. On its own it barely moves blood sugar. Keep to a level tablespoon, choose a no-sugar jar and pair it with wholewheat roti, toast or fruit rather than jam and white bread.
Is peanut butter good for weight gain?
It’s one of the easiest calorie-dense foods to add. Combine it with milk, bananas, eggs and strength work, and see a doctor first if the weight loss was unexplained.
Is peanut butter good for weight loss?
It can fit, if you measure it. It keeps you full, but it’s easy to eat 300 kcal straight from the jar without noticing, so use a level spoon, spread it thin and count it as part of the meal rather than an extra.
Should peanut butter be kept in the fridge?
Natural and homemade peanut butter should go in the fridge after opening, especially in hot weather, to slow rancidity and keep the oil mixed. Jars with stabilisers are fine in a cool cupboard for a few months.
How can I tell if peanut butter is bad?
Smell it. A sharp, paint-like or bitter smell means it’s rancid. Mould, a sour smell or bubbles mean it’s spoiled, and the whole jar goes in the bin.
What are the side effects of peanut butter?
For most people the only real downside is weight gain from large portions, with some bloating in a few. Peanut allergy is the serious one, and it can cause hives, swelling or breathing trouble within minutes.
Is peanut butter good for babies?
Plain, unsalted peanut butter, thinned with water or milk, is a good way to introduce peanut from around 6 months once other solids are going well. Babies with severe eczema or egg allergy should see a doctor first.
Is peanut butter safe in pregnancy?
Yes, if you aren’t allergic, since current advice doesn’t ask pregnant women to avoid peanuts. Choose a clean, reputable brand and count it in your calories, especially if you have gestational diabetes.
Peanut butter vs peanuts: which is better?
Nutritionally, almost the same. Whole roasted peanuts take longer to eat and may fill you up more, while peanut butter is easier to overdo. Pick whichever you’ll portion better.
Peanut butter vs desi ghee: which is healthier?
Peanut butter, because it has protein and mostly unsaturated fat, while ghee is mostly saturated fat with no protein at all, though both are calorie-dense and need measuring.
