I got a few email inquiries from US readers asking what ful was. After much botanical immersion (basically, googling "ful" and "fava bean") I struck gold. Ful is fava bean! And there are several varieties. Read all about it.
And, folks, if you have questions about terms, or measurements, or temperatures, please, please do not hesitate to ask in the comments to the blog. That's what it's there for. This way, others can benefit from the answer to your query, and I get to know that my writing is being read somewhere on the blog, too. :)
