It's a macadamia nut, of course.

I was wondering if anyone knew the name of a certain kind of nut.
Its tree grows in tropical areas, and can be about 60 ft high and about
as wide (including branches) as it is tall. It has big leaves that have
rounded ends.

The nut with its shell is about 3-4 in. long and about
1.5 in. thick, and usually has green or red skin on the outside. It is
shaped like a lemon if you look at it in one way and like a flying saucer if
you turn it around a little bit, and has a ridge around it. The actual nut,
which is edible (and very good-tasting), looks like an almond, but is about
twice as long.
