Was planning on hitting as many tamale joints as I good on my trip in MS, but the demands of a driving schedule eviserated it. However, I did try two and I think I discovered a new one, the best I've had.
Crystal's Grill in Greenwood: tasty with cumin, very moist, with a light tomato/olive oil/steam water sauce.
Solly's in Vicksburg: More solid than Crystal's and with a mild, smoky flavor and a bit of tang. A little bland considering it has won a Hot Tamale award in 2003. Nice place though.
However, the best of the lot has been in Natchez at a Donut & Tamale drive-in at the corner of Homochitto & Junkin Blvd. Moist, strong cumin & spicy. I don't think they are on the Tamale Trail website but I may be mistaken.
Sadly, that is all I have been able to sample. I also tried to go to The Bourbon Mall only to find it closed/out of business. And a long detour for that, too.
