Special Herbs + Spices Vol.
 1 is the third collaboration album released between American rappers MF DOOM and MF Grimm, released in 2004 (see 2004 in music) on Grimm's own Day By Day Entertainment label.
 Unlike their previous works, this CD is solely focused on MF Grimm's rhyming over MF DOOM's production.
 The first ingredient of each song title is a reference to the corresponding track from DOOM's "Special Herbs" series of instrumental albums.
 The tracks on the album were composed as freestyles by MF Grimm with many being written on the spot prior to recording.
 This reflects Grimm's past as a prolific and decorated battle rapper.
 Due to the duo's falling out after the release of this album, it is the last record to be released collaboratively.
