Look for white or bi-color labeled "sweet corn" on the cob. You can use all of the corn from 3 cobs or measure out 1 1/2 cups of the kernels.
Color does not affect the dish flavor or texture, but will impact the final color of the mousse (white vs. pale yellow).
If possible, make this recipe with good quality corn that's in season. It will produce the richest, sweetest flavor.
Snap shot -
In this recipe, you make a crumbly crust out of corn flakes, butter, salt, and sugar -- this is the only thing you bake. You then make a corn infused cream on the stove that gets thickened with mascarpone and whipped cream. The final pie is chilled and served cold with a dollop of whipped cream.
Troubleshooting -
The main issue you could have is adding all of the whipped cream instead of dividing it as the recipe calls for. If this happens, your pie will still turn out, but the strength of the corn flavor will be diluted a bit (more milky).
I made 3 pies to test this recipe and each crust browned slightly differently. Keep watch and pull the crust when it's to your liking (i.e. golden). If you have a super crumbly crust, that's ok. It's likely the result of using corn flakes that were not finely ground enough.
If you like a sweeter pie, I suggest that you add up to 2 tablespoons to the whipped cream because this pie is just sweet (not overly so).Sweet Corn Cream Pie https://thefrayedapron.com/corn-pie
