Every time I make curries or any other Indian recipes they end up tasting bitter. The only thing I can think of is that it has to do with the spices. I have ground my own but that made no difference. I made sure the spice weren't burnt (I thought this would do it). Didn't make a difference. Others who taste the end product say that they taste the bitterness though not as strongly as I do. Please if you have any advice let me know.
