For those of you in the LA basin, or near, there is an excellent tamale factory in San Fernando. It's called the Gourmet Tamale Factory (click for their website). Everyone at our work LOVES it!
They have 7 kinds of tamales:
Chicken in Green Sauce
Beef in Red Sauce
Pork in Red Sauce or Green Sauce
Vegetables—Carrots, Corn, and Peas
If you're ever in the area or need any yummy food for lunch, a party, or a fundraiser, check them out! They also have beans and rice and chile rellenos, etc. Grub!
They also do farmer's markets in New Hall, Burbank, Leimert Park, Silver Lake, Valencia, Encino, and Beverly Hills.
119 N. Maclay Ave.
San Fernando, CA 91340
Bonus - I believe they're run by Christians. (They have John 3:16 on their business cards.)
