|Tassoni soda and Calabresi Cedro di Diamante.|
Here is a great example. Cedrata is not too sweet and the slightly perfumed sour citrus is an interesting combination, Tassoni has been making this soda since 1956 and their signature citron syrup since 1920.
And luckily, albeit only stateside for the moment, they are available on this side of the pond.
We also use it as a mixer.. ahh summer.
