Has anybody used this product (whole or crushed)? I saw Rick Bayless use this on his show (Mexico, One Plate at a Time) and was very curious to know if it is indeed much better for salsas or anything else. Also does anybody happen to know if it's available at Whole Paycheck? I see that it's available at netgrocer online, but I don't really want to pay for postage (of course, compared to WP, it might be cheaper...) Interestingly, it is not available from mexgrocer. TIA.
