In a small bowl, whisk together the tomato paste, water or vegetable stock, and heavy cream until the mixture is completely smooth.
Place a heavy-bottomed saucepan over low heat.
Add the ghee or butter, the whisked tomato-cream liquid, and all remaining EXCEPT for defrosted frozen peas (if using fresh peas, add them now).
Cover the saucepan and let the shorba simmer gently over low heat for 30 to 40 minutes, stirring occasionally.
Cook until the bottle gourd and tomatoes are butter-soft and the liquid has reduced to a thick broth. If needed, add a splash of water to prevent sticking.
If using frozen peas, gently fold them in during the final 2 to 3 minutes of cooking to heat through without losing their vibrant color.
Carefully locate and remove the whole cloves, cinnamon stick, and green chili before serving. Ladle the hot shorba into deep bowls.
