The art of making a delicious, home-baked pie is a step-by-step process that begins with ensuring you are using the appropriate-sized pan for the recipe. Ensuring you have the right pan for the recipe is crucial in order to allow the fillings to expand while baking. Although the most common size of glass pie pans are 22.5 cm (9 inches) in diameter and usually marked, pans might come in various unknown, unmarked sizes. Knowing how to measure the plate correctly will allow you to adjust any recipes and give you the assurance to successfully carry out your recipe.
Place the pie pan down on a flat surface to make sure your measurement will be accurate. Make sure the pan is secured.
Line up the edge of the measuring tape or ruler with the edge of the pie pan's inner circle/bottom. Grip the edge of the pan firmly to ensure the pan does not slip.
Read the measurement from edge to edge of the pan's bottom rim. This is considered the dimension or size of the pie pan. Record the measurement if necessary.
Adjust the pie recipe accordingly based on the measurement of your pie pan. Depending on the recipe, you might need to increase or decrease ingredient measurements to suit the size of your pan.
If you have a pie pan with a retractable bottom, remove the bottom disc and measure from edge to edge. If you have unmarked, aluminium pie pans, use a nontoxic, permanent marker to record the measurement on the underside of the pan for future reference. Flipping your pan upside down might make measuring the pan easier if using a ruler.
