Maaser sheni is intended for the purpose of eating, drinking, and anointing. To eat [only] something that is customarily eaten; to anoint [only with] something that is customarily anointed. One may not anoint [with] wine or vinegar, but he may anoint with oil. One may not spice oil of maaser sheni, and one may not buy spiced oil with maaser sheni money; but one may spice wine. [If] honey and spices fell into it and [the mixture] appreciated, the appreciation is reckoned proportionately. Fish that were cooked with leek-bulbs of maaser sheni and appreciated, the appreciation is reckoned proportionately. A dough of maaser sheni that he baked and it appreciated, the appreciation is to [maaser] sheni. This is the rule: Anything whose appreciation is identifiable, the appreciation is reckoned proportionately; and anything whose appreciation is not identifiable, the appreciation is to [maaser] sheni.
