Sauce – reuse glass bottles with plastic lids for homemade sauces

The sauces are called chutney (plural chutneys).

The green one, called hari chutney in Hindi, is generally made with a mixture of coriander (cilantro) leaves and mint leaves. Hari means green in Hindi. The leaves (I have used them in a 3:1::coriander:mint ratio) are ground to a fine paste along with a tbsp of sugar, a pinch of salt, and about 2 tbsp of lime juice (to prevent oxidation of the ground greens and to provide a tangy taste). Some variations of this may add ginger (for flavor) or peanuts (as a thickening agent) to the mixture.

The red chutney, called imli chutney in Hindi, is very often made with the juice of tamarind (imli in Hindi). Tamarind is soaked in water, strained and mixed with sugar, rock salt, toasted and ground cumin, dry powdered ginger, and powdered pepper. Rock salt and dry ginger give this chutney its distinct taste. Very often restaurants add artificial red color to this chutney to turn the color from brown to red.

It is likely that prior to use there is minimal likelihood of the ingredients separating as the transport and shelf storage of the item is likely considered controlled. Once in a home kitchen, the problem is not with spoilage (there are plenty of preservatives in it), but that storage fluctuations and use may throw the emulsifiers.

Although I am inclined to dismiss the need for refrigerating it, the is likely that across a few million units, a less stable batch may make its way into a hot and then cold and hot and then cold kitchen and the contents would separate.

For big brands, a major focus is to ensure consistency among products in spite of quality or diverse ingredients; hence watery domestic beer (U.S.), Lay's potato chips, and refrigerated chocolate syrup that is harder to use than when stored at room temp.
