Cyn, I caramelized mine in a pan first...using some ghee and a bit of OO. I cooked
them (2 whole) until they were brown and sweet. THEN I added them to the pie.
Crust: I goofed the first time and it worked so well I continued to 'goof' on the second pie. I beat the egg with the salt, added the grated butter, dumped in the flour and just blended with my fingers until done. Dumped it all out on waxed paper and smooshed any remaining flour. Wrapped it up and popped it into the freezer. Unwrapped, added another wax paper on top to roll it out. Perfect both time.
The recipe says to be break the butter into the flour AND THEN add the egg for the moistener. Oops. Well, it worked for me so I'll stick with the goof.
We added three crispy crumbled slices of bacon this time.
