venn piagram

This is a pie a made a few weeks back.  The proportions are of a vesica picsis.  Accordingly the ingredients were adjusted to:

1-\frac{4\pi-3\sqrt{3}}{6\pi} Apple

\frac{4\pi-3\sqrt{3}}{6\pi} Apple/Pear

1-\frac{4\pi-3\sqrt{3}}{6\pi} Pear

I’ll be making a strawberry rhubarb version when the ingredients are in season.
