following up on the project that was left unfinished 9 months ago. cantuccini biscuits. cut half as thick as usual and filled with raisins rehydrated with vin santo. this idea was stumbled upon a while back on studiokitchen. the raisins are pressure cooked with vin santo for 40 minutes. the lid is removed and rest of the vin santo is left to reduce. if you have chosen a good vin santo that is not too sweet you may want to add a handful of sugar to the reducing liquid.
