mjes: Per the indexing guidelines, herbs with no modifier are assumed to be fresh, with one big exception.
From the Chocolate, citrus, herbs & spices section: :: For most herb ingredient names, the “default” format is the fresh herb – basil, cilantro, parsley, dill, etc. The dried version of each herb is usually available as a separate indexable ingredient. Index whichever version is called for, but if fresh vs. dried is not specified in the recipe, choose the default/unspecified version.
NOTE: One exception is oregano, which in EYB refers to the more common dried herb, with fresh oregano available as a separately indexable ingredient. ::
To limit annoyance, do read and re-read the indexing guidelines, and begin to internalize the shortcuts list. To familiarize yourself with defaults, it may help to review the ingredient lists for an indexed books similar to the one you're starting in with (well, scratch that; there aren't many similar). Most ingredients and indexing guidelines aren't going to be re-organized any time soon, because the changes would affect so many recipes.
