Shall I give you white currants?
I do not know why, but I have a sudden fancy for this fruit.
At the moment, the idea of them cherishes my senses,
And they seem more desirable than flawless emeralds.
Since I am, in fact, empty-handed,
I might have chosen gems out of India,
But I choose white currants.
Is it because the raucous wind is hurtling round the house-corners?
I see it with curled lips and stripped fangs, gaunt and haunting energy,
Come to snout, and nibble, and kill the little crocus roots.
This is a very powerful line; The speaker mentions that she doesn’t have much, yet would still choose this little fruit over wealth and riches. 
 The white currants that the speaker chooses are so valuable to her that she would choose them over all else.  This could show either dedication or foolishness, depending on how thought out her decision is. 
 Judging by the previous line where she says she has a  “sudden fancy for this fruit”,  she seems not to have thought much about the decision she’s making.
