All four dishes we've tried so far are simply unbelievably delectable. I've loved Indian for years, and these recipes easily compete with my best restaurant experiences in major cities. They are in ways better than the best I'd had, and certainly worth experiencing yourself if you're into the genre.
(Requires some shopping beyond standard grocery stores for a few ingredients & greatly rewards a food processor. Apart from that, you almost certainly already have what it takes to make these.)
