I want to make Nigella's clementine cake for passover since it has no flour in it. the problem is, clementines are out of season and i can't find them. can i substitute another orange-like fruit?
Would navel oranges work?
How about kumquats?
anyone with any ideas, please let me know. I would like to make the cake tonight or tomorrow morning, as I know it's best if it ages a little.
