Right now the Orchard on Coney Island Avenue is carrying probably the best citrus fruit ever, Ortaniques from Jamaica. the flesh and the rind so perfumed - its a short season so I recommend you check it out now. they are $1 to $1.25 per piece.
I ordered some from Florida last year, but they didnt come up to this level.
they also have some wonderful perfumy tiny muscat grapes just now.
Also the purple asian yams (ube) which, I was surprised to see are creamy colored on the outside - who could imagine the bright purple color inside.
