Very disappointed in this. I have had sambar many times over the years at various Indian restaurants, and this recipe was way off the mark.
The tamarind was too strong, and gave the dish a strong, tangy flavor that was disagreeable.
And the yellow lentils, while edible, were way too firm---and I even soaked them for a couple of hours first, and also cooked them 3X as long as the recipe called for.
I could see maybe using an immersion blender on the lentils to puree them after they've been cooked.
And in my experience, sambar is supposed to have slices of carrot, which this recipe did not have.
I now have a pot of soup that I am not at all enthusiastic about finishing eating, and will probably toss out.
