Bellflower Pistil

The pistil at the top of the Bellflower has a slight fruity and sour aroma, making it quite suitable for making fruit vinegar.

You can purchase Pink Pistil Fruit Vinegar from the Necropolis Mixology Master Rient, then combine it with the Spirit Tree Secret Fruit from the Deep Hidden Valley to create an Unidentified Pink Pistil Fruit Vinegar.
