I have a dry version of poondu milagai podi, which is a semi dry chutney, authentically ground in ammai by coarsely smashing it. Basically its just garlic (with skin) and dark roasted dry red chillies and salt. But as now we all are not using ammi, we add coconut and grind it in mixer, peeling off the skin of garlic too. I just love it a lot than anything for idli, dosa or vendhaya dosai. I love it to mix with curd and have. But my MIL makes a wet chutney with all these grinding smooth as she loves that way and my BILs too likes that more. This time when she made it, I just loved it. For a change it was really good to have it with vendhaya dosai. So I wanted to try too. I ground with little tamarind, but later when I asked her about the recipe, she told no need for tamarind too. I liked the no tamarind version best. So I am adding it to the ingredients list as option, but recommend without tamarind.
Goes well with idli or dosa but best with vendhaya dosai. Also with sponge dosai.
