For best results you will need Omani Lemons which are in fact sun dried limes. In Persian the same name is used for limes and lemons (limoo). Lemon would be called "limoo zard" (yellow lime). So when they translate, they call both limes and lemons "lemon". It is known to Persians that when you say "dried lemons" in English, you really mean "sun dried limes." you can get them at most Middle Eastern/Turkish store.
