Last Sunday, a trip to the 1840s home of writer Edgar Allen Poe in the Fordham area of the Bronx led me to an African grocery across the street and what I found there will be a welcome addition to my gluten-free pantry.

I'm always looking for different gluten-free textures and tastes for my vegetarian meals. Here are links to cuscous recipes I'm considering trying/adapting:
