What it is

Blood orange is a Citrus sinensis variety whose flesh turns deep red from pigments that develop in cool growing conditions.

What it tastes like

On the nose: lemon-citronella-rose, citrus, spicy. Among its measured molecules: beta-thujene, eremophilene, beta-fenchol, α-Cadinene, Citronellal.

Every one of its 15 compounds carries a paper the library can cite.
