Heidi's Maple Buttermilk Pie

Though I'd spotted this pie and pinned it to my recipes to try board a few months ago, I didn't do anything about it until after I'd eaten a slice.

Last month my cookbook club decided to shake things up and try a blog instead of a book. We chose Heidi Swanson's 101 Cookbooks. This Maple Buttermilk Pie was one of the stars that turned up.



The flavour of the filling is difficult to describe. Tangy comes to mind, but it's not sharp like a lemon tart - more of a gentle crème fraîche tang from the buttermilk, muted slightly by the warmth of the maple syrup. The filling sets to a thick and creamy consistency that slices easily.

After failing to write a recipe review post for August I thought I'd loosen it up and do them whenever I come across something interesting that's already online. I loved this pie at cookbook club so it seemed like the perfect thing to make and share with you. The combination of flavours intrigued me so I thought it'd be a good fit for the feel of the series.

I think this pie makes a great autumnal dessert - there's something about maple syrup at this time of year.



Some notes on the recipe:

- I did three turns of the pastry and made a half recipe so I didn't have extra. I didn't have any rye flour so I made it with plain flour. The crimping disappeared as the pastry puffed so I wouldn't bother with it again. I think I might try it with a non-flaky pastry another time (probably this one) - it's quicker and though the top ring of the crust is nice, I prefer non-flaky underneath the pie.

- I wasn't sure about making the filling before the shell had baked or cooled. I think another time I'd make it as the shell cools so that it's ready when it's needed rather than sitting around.

- Normally I make fake buttermilk by adding lemon juice but this time I wanted to have the proper thickness and flavour so I bought some (I found it in my local supermarket next to the milk). It's also worth seeking out grade B maple syrup - it's darker and has a stronger flavour than the normal grade A stuff.

- My filling was set (with a little wobble in the middle) and browning after 50 minutes, so I took the pie out.

- I think the filling tastes best the next day, cold from the fridge - the flavours develop overnight.
