The word(s) "palatable" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) It is He Who has let free the two bodies of flowing water: One palatable and sweet, and the other salt and bitter; yet has He made a barrier between them, a partition that is forbidden to be passed.

(2) Nor are the two bodies of flowing water alike,- the one palatable, sweet, and pleasant to drink, and the other, salt and bitter. Yet from each (kind of water) do ye eat flesh fresh and tender, and ye extract ornaments to wear; and thou seest the ships therein that plough the waves, that ye may seek (thus) of the Bounty of Allah that ye may be grateful.

(3) Were it Our Will, We could make it salt (and unpalatable): then why do ye not give thanks?
