- Make ahead instructions: Prepare the filling as directed above and refrigerate for at least 30 minutes or up to 24 hours before putting the pie together.
- The cream filling does take about 7-8 minutes to thicken in the beginning, so be sure to gently whisk the mixture constantly to avoid scorching the bottom. Just be patient and wait for that magical thickening moment!
- By tempering the eggs before adding them to the filling, you won't get scrambled egg pieces in your pie, but I always strain the mixture before chilling to make sure any impurities are removed. This is the key to a perfectly smooth filling!
- I recommend slicing the bananas about ½" thick. Any smaller, and they seem to get lost in the pie.
