Food for jaguars with savage hearts (5)
I believe the answer is:
guava
'food' is the definition.
(guava is a kind of food)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for guava that I've seen before include "Fruit from South America" , "Pear-shaped tropical fruit" , "Yellow-skinned tropical fruit" , "Tropical tree with yellow fruit" , "Leaving body" .)
