Sweet and salty cooked sooji

Traditional Food of India

4.2.Sweet and salty cooked sooji

Wheat semolina (sooji) and semolina from other cereals and pulses are used to prepare several Indian traditional foods like upmav (salty cooked sooji), halwa (sweet cooked sooji, suji or kesri bath, or kesari bhath), laadu, pani puri, rawa idli and dosa, etc. Among the semolina-based foods, upmav is a ready-to-eat salty sooji popular in South India. The product halwa is a ready-to-eat confectionery possessing a mild sweet taste (Figure 4.2.1). The other names of halwa are halva, halua, halvah, suji, sooji ka halwa, atte Ka halwa and mohan bhog.

The ready-to-eat products are popular throughout India and in neighbouring countries of India, Central and Middle-East countries. They are delicious ready-to-eat products, usually rich in carbohydrate and fat, and are prepared for use as a convenience food, particularly during the morning breakfast. Starch present in the cereal/pulse fractions undergoes the gelatinisation process in the presence of water and heat. The net result is the development of a semi-solid cooked mass obtained from a slurry. A dry mix of instant halwa is commercially available; the mix is partially cooked using a dry or wet cooking process that needs to be boiled for a few minutes to obtain the ready-to-eat form. Multigrain halwa mixes as a convenient product are also prepared from other cereals, millets, legumes, nuts, and condiments; halwa made with artificial sweeteners is also possible. Pumpkin halwa mix has been developed using dried pumpkin powder, sugar and milk powder. Maize semolina-based halwa preparation takes a longer cooking time than conventional wheat-based halwa. The product has an attractive yellow colour but is less popular.

The process of dry roasting on a hot surface favours partial cooking and surface hardening, and helps to maintain the integrity of the cooked semolina particles in the finished product. In the absence of the dry roasting process, the product becomes pasty and sticky. The process of roasting using ghee or oil also serves similar functions in addition to offering a smooth mouthfeel having a pleasant flavour, and avoiding the formation of lumps. Boiling the roasted semolina in water completes the cooking process that is associated with water absorption, volume increase, gelatinisation of starch and leaching loss. The latter two phenomena are restricted when the grits are dry-roasted. Hard wheat having higher protein content than conventional wheat samples is suitable. The fat content of some of the sweet halwas may be as high as 12%.

Some halwa varieties are in the form of dried powdery or gritty samples that can be stored for a long time due to their low moisture content. Examples are atta (whole wheat flour) ka halwa and chana (Bengal gram) dal halwa. People often carry these low-moisture-containing samples during excursions and travel. The simple process of preparation and the low cost of the products are the other advantages.

Raw materials
The main raw material for upmav and kesri bhath is coarse semolina from hard wheat though soft wheat semolina is also used. The other additives are salt, oil/ghee, sugar/jaggery, pieces of nuts (such as groundnut, cashew nut, almond, etc), cooked vegetables (like carrot, tomato, etc), spices (such as chilli, mustard seed, turmeric, ginger, etc), and flavouring items like cardamom, curry leaves, etc.

Method of preparation
Semolina is subjected to mild dry roasting on a hot surface for a short duration, often with a small quantity of oil, fat, butter or ghee. Later, water is added and the mix is boiled for a few minutes to achieve complete cooking. On cooling, the sample attains a semi-solid mass ready for consumption (Figure 4.2.2).

In the case of the preparation of upmav, a small quantity of salt, and cooked vegetable pieces like onion, carrot, tomato, etc are added during boiling in water. On the other hand, sugar or jaggery (gur) is added while pieces of cashew nut and cardamom are added to produce sweet-tasting kesri bhath. The extent of oil/fat addition varies with the consumers in the domestic kitchen or fast food centres. The product has a low shelf-life of 6 hours to one day if stored at an ambient temperature. On rare occasions, a dry free-flowing granular mix or dry semi-solid kesari bhath is prepared that can be stored for a relatively long time of a few weeks. Some people consume these products, prepared in domestic kitchens, during travel, expeditions, and social and religious functions. On occasion, sweet sooji or halwa is an accompaniment to kachuri, a highly popular breakfast or snack item of many people.  

Ready-to-prepare sooji mixes are available that provide convenience to consumers. The advantages of upmav and kesri bhath are the simple method of preparation, nutritious product, minimum time of preparation, and low in cost. However, the shelf-life of these products is low at ambient temperatures.

Machinery
A batch or continuous rotary drum roasting unit, steam-jacketted kettle, a mixing unit like a planetary mixer, and packaging machinery are needed.

Requirements

  • An increase in the shelf-life of the finished product is useful.
  • The development of sweet sooji without using sugar (sucrose) is desired to reach people with diabetes or health-conscious people.
  • Popularisation of salty/sweet sooji using other grains like maize and millet grits can replace the conventionally used wheat.
  • Specification of the product with an emphasis on moisture and fat contents, and microbial status is desired.
