A big thank you to the EYB Indexer who separately indexed all the cake variations in Snacking Cakes by Yossy Arefi. Because of this a cake recipe that was just what I was looking for came up in an ingredient search. If the ingredient, in this case chocolate, had only been noted in Comments I would not have found it. So: Answer to the question: 'If a Variation has a separate title and/or is listed in the Index as a separate recipe it should be indxed as a Recipe and just not noted in Comments'. ???
