Lamb's fry

Lamb's fry is lamb offal served as food, including the testicles, liver, sweetbreads, heart, kidneys, and sometimes the brain and abdominal fat—or some combination of these.

In Australia and New Zealand, lamb's fry is specifically the liver; in the United States, "lamb fries" (q.v.) are specifically the testicles. In the U.K. it was all offal, though recently testicle has become rare.
