I thought I'd prefer to have it listed more like this:
jelly -- strawberry
apple
grape
pear

So in the following snippet, I tried to add a "\n" onto the value of the HoH.
for my $i ( keys %HoH ) {
%{$HoH{$i}} = join ("\n", %{$HoH{$i}}, "");
print "$i -- @{[ keys %{$HoH{$i}} ]}\n";
}

I advise against changing the original keys. The variable $" determines what string is used to separate array elements expanded within a quoted string (read "perldoc perlvar"). I would set $" to "\t\n" before printing.
Good luck.
