What started as a simple request on the DonRockwell.com board has blossomed into a full-fledged Indian crab dinner/book signing/general-foodie-wonkiness dinner at Spice Xing in Rockville on Sunday, July 12.

Sudhir Seth, chef and owner of both Passage to India and Spice Xing, will team up with cookbook author Monica Bhide to offer a three-course dinner completely focused on blue crabs. The feast starts at 6 p.m. with crab tikkis, which are essentially Bhide’s take on Maryland crab cakes, and moves on to pollachi crab masala (crab sauteed in fennel, cinnamon, pepper, and poppy seeds) and crab gassi mangalorean (crab in a curry gravy).

Sandwiched around these courses will be an aperitif called “pomegranate delight” — Bhide’s rum cocktail with pomegranate juice, lime, and grenadine — and a dessert called shrikhand, which is a strained and flavored yogurt with fresh strawberries, kiwi, and mango. The opening course will be in audio form: Bhide will talk about her latest cookbook, Modern Spice, and sign copies.

The whole shebang will set you back $60, which includes a copy of the cookbook. So what’s the catch? You have to go through DonRockwell.com to get your name added to the list. Sounds worth it to Y&H.
