My husband's grandmother was a great cook and didn't always share her secrets, so we are fortunate to have her recipe for rhubarb cream pie. I added one of my favorite crusts and a never-fail meringue.

Chilling pastry dough for a full hour before rolling prevents shrinkage during baking by allowing the gluten strands to relax and the shortening to firm up. Working with cold fat is essential for flakiness, meaning the dough should be handled as little as possible once the water is incorporated. When preparing frozen rhubarb, measure the stalks while solid, thaw them completely, and drain them thoroughly in a colander without pressing out the excess juices, which would otherwise make the unbaked bottom crust soggy.
The filling relies on a rich combination of heavy cream, sugar, and egg yolks poured directly over the raw fruit. Baking this base at 350 degrees for 50 to 60 minutes sets the custard and softens the fibrous stalks. Judge doneness visually by inserting a knife into the center; it should emerge clean without wet custard clinging to the blade. While the pie is baking, cooking the cornstarch and water mixture on the stove creates a stabilizing base that prevents the meringue from weeping.
Incorporating that cooked starch slurry into the whipped egg whites and cream of tartar before adding sugar provides structural insurance for the topping. Spreading this warm meringue over the hot filling creates a thermal bond that stops the foam from shrinking back toward the center during its final 15 minutes in the oven. Once golden brown, the dessert requires a full one-hour cooling period on a wire rack before refrigeration to let the custard finish setting.
