Sign pastries include small currants initially (6)
I believe the answer is:
pisces
'sign' is the definition.
(Pisces is an example)
'pastries include small currants initially' is the wordplay.
'pastries' becomes 'pies' (pie is a kind of pastry).
'include' indicates putting letters inside.
'initially' says to take the initial letters.
The initial letters of 'small currants' is 'sc'.
'pies' going around 'sc' is 'PISCES'.
(Other definitions for pisces that I've seen before include "Spice for the Fish" , "Twelfth zodiacal sign" , "The twelfth sign of the zodiac, the fishes" , "stars" , "Fish star sign" .)
