As the newest aspiring bakerette on the block, I am literally going bananas with all the options and items out there for baking. As it happens, I am obviously looking at pie dishes more than anything else. Oh, and flour (so many types of flours!!). The pie dishes that have really stolen my heart are the Emile Henry pie dishes. They are sit down and take my money BEAUTIFUL. But they have one caveat I have noticed the more I obsess over them. The real stunner dishes are NOT 9-inch pie dishes. So what is one to do in such a situation?
Most pie recipes are made, and specify they are made, for 9-inch dishes. Wanting to use my pretty pie dishes, it is stressful. Should I double the recipe? What do I do? Back to my trusty Google I go. This is what I found. As a disclaimer, I’ve only done one pie in my Emile Henry pie dish which was ironically sold as a 9-inch dish but really is 10-inches. And I very newbie-like made twice the dough for the crust but didn’t make more of the chocolate cream filling. Pie came out just fine, but definitely could have used more filling.
I was surprised at how little information there is on this subject. It made me think if this issue of converting isn’t such a big deal and I’m basically drowning in a glass of water about it. OR no one wants to deal with the conversions. Conversions can be tricky and may not come out right if you mess up just one part of the calculation. Math is not forgiving!
There are two articles/blog posts I found that I thought were very useful and made the conversions between different size and shape plates easier. Of the two posts, the posts from Coco and Me made the most sense to me personally.
Here is the secret sauce formula:
(Volume of the plate you want to use) / (volume of the plate in the recipe)
How do we get volume? Easy!
Ever heard the term pie-r-squared? That would be pi (3.14), r = radius of the pie dish (half of the diameter), and squared (multiply the radius-r by radius). So you multiply the pi with the radius (half of the diameter) multiplied by the radius.
So: Volume of a round plate is = 3.14 X (radius X radius) X height of pie plate
Square or Rectangle
Volume for a square or rectangle is the length multiplied by the width multiplied by the height.
Volume = length X width X height
Now I would go as far as if you have an irregular shaped plate (say an Emile Henry heart-shaped pie plate) that has the length and width in its description, you can also use this formula to estimate the volume.
If you don’t feel fuzzy inside using the square-rectangle volume formula for an irregular shaped plate, you can fill up the plate and get the volume that way. Just convert it back to cubic centimeter or cubic inches to use in the first formula.
So that’s it! Easy as pie! (yea right). I’ll be trying this conversion with my spankin new heart-shaped dish for my Valentine’s Day recipe. I’ll share my thoughts about that on that blog post.
If you try this out, let me and Tamami from Coco and Me know if it works!
