A spoonful of ghee on hot rotli has a visible job: it melts, spreads and carries an aroma. In another passage, ghee may be the base of a prepared medicine. In a third, a lamp is filled with it before worship. The substance is recognisable across all three scenes, but its purpose changes.
Read the verb beside the ingredient. Is the writer cooking, offering, or prescribing? A family recipe belongs with other kitchen records. A medicinal preparation raises additional questions about what else is in it, who prepared it and for whom it was intended.
Photographing a family ghee pot can preserve details that an ingredient list misses: the size of the household, the spoon kept beside the stove and the occasions when a fresh batch was made. That is a richer account than treating every reference to ghee as an endorsement of taking it in medicinal quantities.
