I have a question about the parts of citrus fruits which just occurred to me as I was eating an orange this morning. Is the word قشرة used for both the rind (e.g. of an orange) and the pith (the white part inside that is still bitter and largely inedible)? This seems to be what dictionary results are turning up for me. Is there a common way to distinguish between the two? Both فصحى and colloquial responses are welcome. Thanks!
