A lemon meringue pie's sweet froth and tart citrus is a heavenly combo. The techniques aren't difficult, but they do ask for some organization and patience because a freshly whipped meringue needs to go on a still-warm filling to help "cook" the egg whites.

Yet, the whole process doesn't take long once all the ingredients are in place - and there's something satisfying about having everything ready at your fingertips.

Start by pre-baking the crust. Roll out a favorite homemade recipe or choose one of the excellent ready-mades in the dairy or freezer case. Prick the bottom several times with a fork, then lay a sheet of aluminum foil in the pan and pour in some dried beans to keep the empty crust from bulging in the hot oven.

Now, assemble two stations: one with the filling ingredients, and the other with the meringue ingredients. The common factor is eggs, divided, with the yolks for the filling and the whites for the topping.

Make the filling first, bringing the ingredients to a boil. Stir constantly and briskly to keep any lumps from forming. Don't be timid, for it will thicken quite suddenly.

Here comes the first need for patience. You can't dump the yolks into the hot filling all at once or they'll curdle. The solution is to warm them a bit by adding several spoonfuls of hot filling, whisking all the while. Then the warmed yolks can be whisked into the pan of filling and cooked a few more minutes until thick.

Now to the meringue, and the second need for patience: The sugar must be added slowly enough to fully dissolve. We're talking about only a few minutes, but when you're dribbling sugar into a mixer, it's tempting to hurry things along. Don't.

Meringues are simply egg whites, cream of tartar and sugar, but for the loftiest and stablest pompadour, we also add a paste of cornstarch and water, cooked until just thickened.

This pie needs to thoroughly cool on a wire rack for several hours, but that means it can be done early in the day and held in the refrigerator. A final tip: Slicing it with a sharp knife dipped in hot water will make the cleanest cut.

Now you can think of heaping meringue on all sorts of pies, from sour-cream/raisin to key lime to chocolate pudding.

The sky's the limit.

Lemon Meringue Pie

Serves 8.

For the cornstarch paste:

• 1 tablespoon cornstarch

• 1/3 cup water

For the crust:

• Homemade or pre-made pie crust for 9-inch pie

For the filling:

• 2 to 3 teaspoons grated lemon zest (from 2 lemons)

• 1/2 cup strained lemon juice (from 2 to 3 lemons)

• 4 egg yolks

• 1 1/4 cup sugar

• 1/3 cup cornstarch

• 1/8 teaspoon salt

• 1 1/2 cup water

• 2 tablespoons unsalted butter, in small pieces

For the meringue:

• 4 egg whites

• 1/4 teaspoon cream of tartar

• 1/2 cup superfine sugar

• 1/2 teaspoon vanilla

Using your smallest pot or saucepan, combine the cornstarch and water. Stirring briskly, bring to a boil until just translucent. Do not overcook. Scrape paste into a small bowl and cover. Set aside.

For the crust: Preheat oven to 400 degrees. Place dough in pie plate and crimp edges as desired. Prick dough several times with a fork. Place a piece of aluminum foil onto the dough and pour in about a cup of dried beans; this will keep the crust from bulging while baking. Bake for 7 minutes, then remove foil and beans and continue baking for 5 minutes. Place crust on wire rack to cool. Reduce oven to 350 degrees.

For the filling: Grate the zest from two lemons to measure 2 to 3 teaspoons. Squeeze lemons to make 1/2 cup juice. Separate eggs, placing yolks in a small bowl and the whites in the bowl of a mixer.

In a medium saucepan, whisk together sugar, cornstarch, salt and water. Over medium heat, and stirring constantly, heat mixture until very thick, about 2 to 3 minutes. Remove from heat.

Whisk lemon juice into the egg yolks. Carefully add a spoonful of the hot filling to the yolks, immediately whisking to combine. Repeat with 2 more spoonfuls. Then, whisking constantly, slowly pour the egg yolk mixture back into the filling. Return to medium heat and cook until very thick, stirring constantly. Remove from heat. Stir in butter and lemon zest. Set aside.

For the meringue: Mix egg whites and cream of tartar on medium speed until very frothy, about a minute. Slowly begin adding the sugar, a spoonful at a time. It should take you about 2 minutes to add all the sugar. Increase speed and continue beating until whites hold stiff peaks. Reduce speed to low. Add vanilla, and the cornstarch paste, 1 tablespoon at a time. Return to medium speed for about 30 seconds.

Pour filling into the pie shell. Spoon dollops of meringue around the edge, making sure there are no gaps between the crust and the meringue. Pile the remaining meringue onto the filling. Create a few curlicues by dipping the back of a spoon into the meringue and pulling up to create a curl. Don't overwork.

Bake pie for 15 to 20 minutes, or until meringue is light brown. Let cool completely on wire rack, then refrigerate.
