The Art of Making Gulabjamun: Ingredients, Methods, and Quality Factors

Gulabjamun is one of India’s most beloved sweets – soft, syrup-soaked spheres with a rich, mildly caramelised flavour that feature in almost every celebration, from Diwali to weddings. Made primarily from khoa (concentrated milk solids), refined wheat flour (maida), and a pinch of baking powder, these golden-brown balls are deep-fried and then dunked into fragrant sugar syrup until they turn juicy and succulent. Whether prepared by a neighbourhood halwai or on an industrial assembly line, the science and craft behind a perfect gulabjamun are surprisingly precise. Let’s break down the ingredients, preparation methods, quality benchmarks, and shelf life of this iconic dairy-based sweet.

What exactly is gulabjamun? 🔗

Gulabjamun is a spherical, deep-fried sweet made from milk solids soaked in sugar syrup. The word itself is a combination of two Hindi-Urdu terms: “gulab” (rose), referring to the rose water often used to flavour the syrup, and “jamun” (Indian blackberry), describing the plum-sized shape and colour of the finished product. It is classified as a khoa-based indigenous dairy sweet and remains popular across all regions of India.

The ideal gulabjamun has a brown exterior, smooth spherical shape, soft and slightly spongy body, uniform granular texture, and a mildly cooked flavour. It should be completely saturated with sugar syrup, delivering optimum sweetness in every bite. A piece of raisin (kishmish) or cashew nut may sometimes be placed at the centre for added richness.

Key ingredients and their roles 🔗

Khoa (mawa) 🔗

Khoa is the primary ingredient and the source of gulabjamun’s characteristic milky richness. It is prepared by slowly evaporating moisture from full-cream milk – traditionally buffalo milk – until only semi-solid milk solids remain. The Dhap variety of khoa, which retains about 40-45% moisture and has a soft, spreadable consistency, is preferred for gulabjamun preparation. The higher moisture content in Dhap khoa makes it easier to form a pliable dough that fries evenly without cracking. According to NDDB, khoa can be produced using semi-mechanised processes involving condensing units and mechanised khoa-making machines, significantly reducing time and labour compared to the traditional open-pan method.

Maida (refined wheat flour) 🔗

Maida acts as a binding agent. It holds the crumbled khoa together and gives the dough enough structural integrity to form smooth, crack-free balls. Too little maida and the balls may disintegrate during frying; too much and the finished gulabjamun will taste doughy and heavy. In the traditional formulation, roughly 250 g of maida is used for every 750 g of khoa – a ratio of about 1:3.

Baking powder 🔗

Baking powder is the leavening agent. It generates carbon dioxide gas when exposed to heat and moisture, which makes the fried balls expand, absorb syrup better, and develop the desired soft, spongy texture. The quantity must be precise – about 5 g for 750 g of khoa. Excess baking powder causes balls to become too soft, break apart during frying, or leave a bitter aftertaste. Too little results in dense, hard gulabjamun that do not absorb syrup properly.

Sugar syrup 🔗

The syrup is prepared by dissolving sugar in water and boiling it to a slightly sticky consistency – typically around 60° Brix – without reaching a full string consistency. Flavourings such as cardamom, saffron, and rose water are added to the syrup. A few drops of lemon juice are commonly included to prevent the syrup from crystallising. The temperature of the syrup at the time of soaking is usually maintained at around 60°C, which allows the fried balls to absorb it evenly.

Frying medium 🔗

Gulabjamun can be fried in either refined vegetable oil or ghee. Ghee imparts a richer, more traditional flavour. The frying temperature is a critical control point – the oil should be heated to about 140°C. If it is too hot, the balls will brown on the outside while remaining raw inside; if it is too cool, they will absorb excess oil and become greasy.

Traditional method of preparation 🔗

The traditional method is a small-scale batch process used by halwais (confectioners) across India. Here is the step-by-step process:

Step 1 – Prepare the dough. Crumble or grate Dhap khoa finely. Combine it with sifted maida and baking powder. Mix gently – the key word is gently. Over-kneading activates gluten in the flour, which toughens the dough and produces hard gulabjamun. A small amount of water or milk can be added if the dough feels too dry. The final dough should be soft, smooth, and completely free of cracks.

Step 2 – Shape the balls. Divide the dough into equal portions (roughly 8-10 g each) and roll them into smooth spheres. The surface must have no cracks at all – any crack will cause the ball to split open during frying. Greasing the palms lightly with ghee helps achieve a smooth finish. A piece of raisin or cashew can be placed in the centre before sealing.

Step 3 – Fry. Heat oil or ghee to approximately 140°C. Slide the balls in gently and fry on a low flame, continuously rotating them with a slotted spoon so they cook and colour evenly. Frying takes about 7-10 minutes until they reach a deep golden-brown colour.

Step 4 – Soak in syrup. Transfer the fried balls immediately into warm sugar syrup (around 60°Brix). The balls need to soak for at least 2 hours to fully absorb the syrup. When completely soaked, the gulabjamun will settle at the bottom of the syrup tank, indicating they are ready.

The dough mix should be prepared fresh every time – storing it leads to drying, which makes crack-free ball formation nearly impossible.

Mechanized method of production 🔗

For large-scale commercial manufacturing, a mechanised semi-continuous system has been developed. The National Dairy Development Board (NDDB) pioneered this technology, and it has been successfully deployed at facilities like Sugam Dairy in Vadodara, Gujarat.

How the mechanized process works 🔗

The process uses a planetary mixer to blend khoa (with 35-40% moisture), approximately 20% maida, and 0.5% baking powder into a homogenous dough. Once the dough reaches the correct consistency – judged by whether it can form smooth, crack-free balls – it moves to a portioning machine that divides it into uniform portions of about 8 g each.

These portions are conveyed to a ball-forming machine (adapted from meatball-forming equipment used in food processing). The shaped balls then travel on a conveyor into a continuous frying vat containing edible oil maintained at 140°C. After frying to the proper colour and doneness, the balls are transferred to a sugar syrup tank at 60° Brix. Once the balls have fully absorbed the syrup and settled, they are packaged.

This assembly-line approach ensures uniform size, shape, and colour across every batch – something that is difficult to achieve consistently in manual production. It also reduces labour costs and increases output significantly.

Quality parameters of good gulabjamun 🔗

Quality evaluation of gulabjamun involves assessing several sensory and physical characteristics. Here is what defines an ideal product:

Colour: Uniformly brown on the outside. Uneven browning indicates inconsistent frying temperature.

Shape: Smooth and spherical. Surface cracks or irregular shapes point to dough preparation issues.

Body and texture: Soft and slightly spongy, with a uniform granular texture throughout. There should be no lumps and no hard central core – a hard centre means the ball was either too large, the oil was too hot, or the frying time was insufficient. The product should also be free from any doughy feel, which indicates incomplete cooking.

Flavour: Mildly cooked and slightly oily, with the sweetness of sugar syrup and the aroma of cardamom, saffron, or rose water coming through. No bitter aftertaste (which would signal excess baking powder).

Syrup absorption: The gulabjamun should be fully succulent – completely soaked through with syrup, with optimum sweetness. A dry or partially soaked gulabjamun is considered a defect.

As per standards referenced by FSSAI’s guidance note on traditional milk sweets, gulabjamun must be prepared from khoa, skimmed milk powder, milk powder, ghee, cream, butter, or other milk solids. It may contain maida, citric acid, and baking powder, and must be free from dirt, foreign matter, insects, and mould growth.

Chemical composition 🔗

The chemical composition of gulabjamun varies depending on factors like the quality of khoa used, the proportion of ingredients, and the concentration of sugar syrup. On a drained-weight basis (i.e., the weight of the ball after removing excess syrup), the composition typically falls within these ranges: moisture content around 25-35%, fat content between 10-18%, protein in the range of 5-10%, and total sugars forming the bulk of the remaining weight. The exact values vary based on whether cow or buffalo milk khoa is used, since buffalo milk khoa has a higher fat content.

Common defects and troubleshooting 🔗

Hard gulabjamun 🔗

This is the most common complaint. Hard balls are usually the result of over-kneading the dough, using too much maida relative to khoa, too little baking powder, or frying at too high a temperature (which cooks the surface rapidly while leaving the inside undercooked). If the khoa itself is too dry or of poor quality, the resulting dough will lack sufficient moisture for proper expansion during frying.

Balls cracking or breaking during frying 🔗

Cracks on the surface of uncooked balls allow oil to seep in, causing the gulabjamun to split apart in hot oil. The solution is to ensure the dough has enough moisture and that balls are rolled gently into perfectly smooth spheres with no surface cracks.

Balls disintegrating in syrup 🔗

This usually happens when excess baking powder has been used or when the dough is too soft. The over-leavened structure cannot hold together once it begins absorbing syrup.

Sugar syrup crystallisation 🔗

If the syrup turns grainy or crystallises after cooling, it likely has been boiled too long or lacks an acidic ingredient. Adding a small amount of lemon juice or citric acid to the syrup prevents crystallisation.

Packaging and shelf life 🔗

At room temperature, gulabjamun kept in sugar syrup lasts about 5-7 days. The high sugar concentration of the syrup (60° Brix) acts as a preservative by reducing water activity, which limits microbial growth.

For extended shelf life, manufacturers use several approaches. Hot-filling in pre-sterilised polystyrene tubs, combined with the addition of 0.1% potassium sorbate as a preservative, can extend shelf life to approximately 3 weeks at room temperature. For even longer storage, gulabjamun can be packed in metal cans after being run through a steam chest for 7-8 minutes. This thermal processing can give the product a shelf life of up to 6 months at room temperature. NDDB notes that when packed in tin containers, the product can last up to 9 months under proper storage conditions.

Gulabjamun mix: an alternative base 🔗

During summer months and festive seasons, fresh khoa may not always be available in sufficient quantities. To address this, instant gulabjamun mixes were developed – first by the Central Food Technology Research Institute (CFTRI), Mysore, using spray-dried skimmed milk powder, maida, vanaspati, citric acid, tartaric acid, and baking soda. A similar formulation was later developed at the National Dairy Research Institute (NDRI), Karnal, using roller-dried skimmed milk. These instant mixes are now commercially produced by several brands and have BIS standards (IS 12220-1987) governing their composition.

The advantage of these mixes is convenience – the user simply adds water, forms the dough, and proceeds with frying and soaking. However, gulabjamun made from fresh khoa is generally considered superior in taste and texture compared to mix-based versions.

Why gulabjamun matters to India’s dairy economy 🔗

Gulabjamun is more than just a dessert – it represents a significant value-addition opportunity for the dairy sector. Traditional Indian dairy products add roughly 200% value to milk, compared to about 50% for most western dairy products. The raw material cost for gulabjamun is estimated at about 34% of the selling price, making it a highly profitable product for dairy cooperatives and small businesses alike. With NDDB’s mechanised technology now available for adoption by cooperative dairies, scaling up production while maintaining quality has become more feasible than ever.

What do you think? Given the growing demand for packaged Indian sweets, do you believe mechanised production can truly match the taste and texture of traditionally handmade gulabjamun? And how important do you think standardisation of quality parameters is for building consumer trust in commercially produced khoa-based sweets?
