Start by carefully washing all the vegetables. Keep the skins on the vegetables, the pods on the peas, and the stems on the eggplants.
Next, wash the daal really well. Some like to soak the daal beforehand, but my mother never did, and I follow her lead.
Place the daal in a large pot, add enough water to cover it, and cook until it's about a third of the way soft – around 30 minutes.
Then, add the potatoes, followed by the sweet potato, hyacinth beans, peas, baby eggplants, and baby spinach, waiting about 10 minutes between each addition.
Cover the pot and cook over medium heat for about an hour to an hour and a half.
You want the daal and vegetables to be tender but still hold their shape.
This took me about an hour and twenty minutes.
You could pressure cook it, but I prefer the traditional method for Gota Sheddho. If you pressure cook, 2 whistles are enough.
