The Gujarati element of the recipe is the liberal use of a variety of Indian spices and condiments, in contrast to the more mellow Iranian recipes. In Parsi homes, dhansak is traditionally made on Sundays owing to the long preparation time required to cook the lentils and vegetables into a mush (in the days before pressure cooking was employed). Dhansak is also always had on the fourth day after the death of a near one. There is no meat
Pulse-amplitude modulation Pulse-amplitude modulation Pulse-amplitude modulation (PAM), is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulses. It is an analog pulse modulation scheme in which the amplitudes of a train of carrier pulses are varied according to the sample value of the message signal. Demodulation is performed by detecting the amplitude level of the carrier at every single period. There are two types of pulse amplitude modulation: Pulse-amplitude modulation is widely used in modulating signal transmission of digital data, with non-baseband applications having been largely replaced by pulse-code modulation, and,
