plantain substitute
in pie crust.
Plantain defines the filling that Pie Crust holds, contributing juiciness and sweetness. The substitute must set similarly when baked inside the shell.

adjustment for this dish
Roasted sweet potato at 1:1 cup is drier than plantain and releases only 40% as much syrup during baking. Skip the 20-minute maceration and go straight to filling; add 1 tablespoon melted butter per cup to restore richness. The flaky pea-size butter pockets in the crust stay dry from below — no soggy bottom risk.

adjustment for this dish
Ripe jackfruit at 1:1 cup is fibrous and very juicy — double the cornstarch to 4 teaspoons per cup and macerate 30 minutes to drain thoroughly. Reduce the drained syrup by two-thirds before returning; jackfruit syrup is thinner than plantain's. The crimped crust needs a 45-minute chill before oven because jackfruit filling boils aggressively.

technique for pie crust
technique
Plantain is the filling in this dish, not the fat, so technique is about controlling its water release against a cold-butter crust that must stay flaky. Slice barely-ripe plantain 6mm thick, macerate with 3 tablespoons sugar and 2 teaspoons cornstarch per cup for 20 minutes, and drain off the expelled syrup (reduce that syrup by half and pour back).
This prevents the pea-size butter pockets in the crust from being soaked from below. Blind bake the shell at 400°F with pie weights for 15 minutes, dock the base, then add filling and bake at 375°F for 35 minutes.
Unlike plantain in scones where cold diced plantain is folded into a dry dough that bakes together in 18 minutes, plantain in pie-crust sits as a wet filling under a lamination for 50 minutes — hydrate management is everything. Crimp the edges high to contain the bubbling juice and chill the filled, unbaked pie for 30 minutes before it goes in the oven so the butter in the crimp re-firms.
A tender shell under juicy plantain requires that drain-and-reduce step; skipping it guarantees a soggy bottom.
pitfalls to avoid
watch out
Don't skip macerating the plantain with sugar and cornstarch for 20 minutes — undrained fruit releases its juice into the crust and soaks the flaky pea-size butter pockets from below.
watch out
Blind bake the shell 15 minutes with pie weights and dock the base before filling; an unbaked crust under juicy plantain guarantees a soggy bottom no matter how cold the lamination started.
watch out
Chill the filled pie 30 minutes before it hits the oven so the butter in the crimp re-firms — warm crimp melts out in the first 5 minutes and the edges slump flat.
watch out
Reduce the drained syrup by half and add it back as concentrate; pouring raw drained syrup back in negates the maceration and the filling bubbles through the crust.
watch out
Rest the baked pie at least 3 hours before slicing so the cornstarch sets — cutting at 30 minutes releases a hot flood that re-wets every layer of the tender shell.
