Rinse the plums and the figs and remove any stems.
Cut the plums into 1/2 inch slices. I like to keep the skin on the plums so that the plum slices retain their shape and to prevent the plums from becoming applesauce-like in consistency.
Remove the stems/firmer ends of the figs and cut into quarters.
In a large bowl combine the plum slices, figs, and thyme leaves.
Add the granulated sugar, cornstarch, and salt. Mix to combine well. Allow the mixture to rest for 10 minutes. When filling the pie, be sure to leave the liquid behind - we do not want a soggy bottom!
Don't forget to egg wash the top of your pie after you have assembled the top crust. Bake the pie as per the instructions on her post.
