Rhubarb Custard Tart

Rhubarb Torte

So I came across this picture more than a year ago, and fell head over heels in love with it. but alas, no recipe to go along with it. So I became a woman on a mission, trying to find something that would more or less match up, and I think I did. I played around with a few different recipes and settled on the one below, taking a bit from this one and a bit from that one. I have given an recipe for making your own pastry dough, but you can easily just use a store bough one instead. Just blind bake until golden brown and follow the rest of the steps for the tart.

Ingredients:

Sweet Pastry Dough:
1 ¼ cups all-purpose flour
1 ½ tablespoons sugar
¼ teaspoon salt
7 tablespoons cold unsalted butter, cut into bits (1 stick, minus 1 tablespoon)
1 large egg yolk
½ teaspoon vanilla
½ teaspoon lemon juice
2 ½ tablespoons cold water

Custard:
414ml (14 oz.) condensed milk (this is equal to 1 ¾ cups plus 2 tablespoons)
100ml evaporated milk (this is equal to ½ cup minus 1 tablespoon)
1 teaspoon vanilla
2 tablespoons cornstarch
2 eggs + 2 yolks

Rhubarb:
2-3 large stalks fresh rhubarb, sliced to the width of your tart pan
¼ cup sugar
¼ cup water

You will also need a 14 x 5 x 1 inch rectangular tart case (or any other tart shell you would like)

Directions:

For the Pastry Dough:
Whisk together the flour, sugar, and salt in a large bowl. Using a pastry blender or your fingertips (or I’ve even known people to use two knives in a criss-cross motion), blend together the flour mixture and butter until most of mixture resembles coarse meal with small (roughly pea-size) butter lumps.

In a separate bowl, beat together the egg yolk, vanilla, lemon juice, and water with a fork and then stir it into the flour/butter mixture with the fork until combined well.

Gently knead the dough in the bowl with floured hands until a dough forms. Turn the dough out onto a floured surface and gently knead 4 or 5 times. Form the dough into a ball, and then flatten it into a disk and chill, wrapped in plastic wrap, at least 1 hour and up to 2 days.  If making the tart right away, preheat oven to 350°F, and line a rectangular pastry case with sweet pastry and blind bake* until golden, about 12-15 minutes.

For the Custard:
To make the custard you are going to need to pans on the stove top at once. One with the evaporated milk/cornstarch mixture and one acting as a double boiler* for the egg base.  For the egg base, take a small to medium pan (make sure your pan is smaller than your mixing bowl that will sit on top) and put a cup or two of water in it and set it to boil on the stove. Once it begins to boil, lower it to a simmer. It is now ready to act as your double boiler.

While you are waiting for your water to come to temperature, mix the eggs, egg yolks, vanilla and condensed milk together in a glass bowl. Once the water is simmering, place the glass bowl over the pan, and heat the contents, whisking until they thicken. To make the custard place the evaporated milk and cornstarch in a saucepan and slowly bring to a boil, stirring constantly.

Remove both mixtures from the stove top and fold together to fully combine. Pour the combined custard into the cooked pastry case.

For the Rhubarb:

Cut the rhubarb into equal lengths, to fit the pastry case. Pour the sugar and water into a sauce pan and heat until the sugar has dissolved. Place the rhubarb into the heated sugar and allow to cook for 1 minute then turning gently for another minute. You are just par-cooking the rhubarb, the final product will still have some firmness to it.

Place the rhubarb gently on top of the custard along the length of the pastry case. Using a pastry brush, brush the top of the tart and rhubarb with the remaining sugar syrup to glaze. Refrigerate until chilled and set.

Sauce 5 – Hollandaise Sauce

Hollandaise SauceHollandaise sauce is an emulsion of egg yolk and liquid butter, usually seasoned with lemon juice, salt, and a little white pepper or cayenne pepper. In appearance, it is light yellow and opaque, smooth and creamy. The flavor is rich and buttery, with a mild tang added by an acidic component such as lemon juice, yet not so strong as to overpower mildly-flavoured foods. This recipe will make about 2 cups of sauce.

Ingredients:

1 cup clarified butter (about 2½ sticks before clarifying)
4 egg yolks
2 tablespoon lemon juice (the juice from 1 small lemon)
1 tablespoon cold water
Kosher salt, to taste
Cayenne pepper (or a dash of Tabasco sauce), to taste

Directions:

Heat an inch or two of water in a saucepan over a medium heat. Also, your clarified butter should be warm, but not hot. Combine the egg yolks and the cold water in a glass or stainless steel bowl (not aluminum) whisk for a minute or two, until the mixture is light and foamy. Whisk in a couple of drops of lemon juice, too. The water in the saucepan should have begun to simmer. Set the bowl directly atop the saucepan of simmering water. The water itself should not come in contact with the bottom of the bowl. Whisk the eggs for a minute or two, until they’re slightly thickened. Remove the bowl from the heat and begin adding the melted butter slowly at first, a few drops at a time, while whisking constantly. If you add it too quickly, the emulsion will break. Continue beating in the melted butter. As the sauce thickens, you can gradually increase the rate at which you add it, but at first, slower is better.

After you’ve added all the butter, whisk in the remaining lemon juice and season to taste with Kosher salt and cayenne pepper (or a dash of Tabasco sauce). The finished hollandaise sauce will have a smooth, firm consistency. If it’s too thick, you can adjust the consistency by whisking in a few drops of warm water. It’s best to serve hollandaise right away. You can hold it for about an hour or so, provided you keep it warm. After two hours, though, you should toss it — both for quality and safety reasons.

Bernaise SauceBéarnaise Sauce

Béarnaise is a rich, buttery, aromatic sauce featuring shallots, tarragon and crushed black peppercorns. It’s one of the most amazing sauces to serve with a grilled steak. If you will be serving this sauce with meat, and you keep kosher, instead of using butter, you should use margarine so that the sauce remains pareve (non-dairy). This recipe will make about 2 cups of sauce.

Ingredients:

1 cup clarified butter (about 2½ sticks before clarifying)
4 egg yolks
½ cup white wine vinegar
½ teaspoon crushed black peppercorns
2 tablespoons chopped shallots
1 tablespoon chopped tarragon*
1 tablespoon chopped chervil (or parsley)*
Kosher salt, to taste
Cayenne pepper (or a dash of Tabasco sauce), to taste
Lemon juice, to taste

Directions:

Heat an inch or two of water in a saucepan over a medium heat. Also, your clarified butter should be warm, but not hot. In a separate saucepan, heat the vinegar, shallots, peppercorns and half of the tarragon to a simmer and reduce until the mixture is nearly dry (au sec). There should be about two tablespoons of liquid remaining. Remove from heat and transfer to a glass or stainless steel bowl (not aluminum). Add the egg yolks and whisk for a minute or two, until the mixture is light and foamy. The water in the saucepan should have begun to simmer. Set the bowl directly atop the saucepan of simmering water. The water itself should not come in contact with the bottom of the bowl. Whisk the egg-vinegar mixture for a minute or two, until it is slightly thickened. Remove the bowl from the heat and begin adding the melted butter slowly at first, a few drops at a time, while whisking constantly. If you add it too quickly, the emulsion will break. Continue beating in the melted butter.

As the sauce thickens, you can gradually increase the rate at which you add it, but at first, slower is better. After you’ve added all the butter, strain the sauce into a new bowl, stir in the chervil and the remaining tarragon. Season to taste with lemon juice, Kosher salt and cayenne pepper (or a dash of Tabasco sauce). The finished béarnaise sauce will have a smooth, firm consistency. If it’s too thick, you can adjust the consistency by whisking in a few drops of warm water. It’s best to serve béarnaise right away. You can hold it for about an hour or so, provided you keep it warm. After two hours, though, you should toss it — both for quality and safety reasons.

Chantilly SauceChantilly Sauce

The Chantilly Sauce is a classic sauce made by adding stiffly whipped cream to a basic Hollandaise sauce. Sometimes called Mousseline sauce, it can be served with seafood, vegetables or poultry, or, sweetened, on crepes and other desserts. The Chantilly Sauce can also be made with whipped egg whites instead of whipped cream. This recipe will make about 2 cups of sauce.

Ingredients:

1 pint Hollandaise sauce
½ cup heavy cream

Directions:

Whip the cream until it forms stiff peaks, then fold it into 1 pint Hollandaise sauce. Serve right away.
