Step 1

To make in a processor:   Place the flours and baking powder in the food processor.   Process to mix briefly.  Place the butter in a circle over the flours.  Process until finely cut in.  Add the sugar; process briefly.  Add the egg and yolk and process until a ball forms.

Step 2

To make in a mixer: Combine the flours, baking powder and butter in mixer bowl. Beat with the paddle attachment until the butter is cut in very finely.  Add the sugar; mix briefly.  Add the egg and yolk; mix on medium speed until it comes together in a ball.

Step 3

Spray only the center bottom of the pan only with a releasing spray.

Step 4

Save a small piece of dough about the size of a large marble in case the crust needs to be patched.  Divide the remaining dough in half (175 grams or 6 ounces).  Divide one piece in half again (85 grams or 3 ounces).  Roll one quarter of the dough (85 grams or 3 ounces) evenly into a rope.  Lay against one half edge of the pan.  Repeat with the other quarter, overlapping the pieces slightly. Press into the side of the shell, sealing the two pieces together.

Step 5

Flatten the remaining half of the dough into a circle.  Place it in the bottom of the pan.  With the heel of your hand, press the dough outward toward the edge.  Continue to work the dough outward with your fingers and lastly, seal the seam.  Be sure to seal the seam well where the edge and the bottom meet so it does not crack when baked.

Step 6

Prick the tart bottom with a fork.  Place on a baking sheet and bake for 12 to 15 minutes if partially baking or 18 to 22 minutes until a rich golden brown if fully baking.  Cool; fill and finish as directed.

Step 7

If cracks appear, use the reserved dough to patch them with a small spatula while the pastry is hot. There is no need to bake it again.

Step 8

The unbaked pastry shell can be made several months in advance, frozen in its pan, and wrapped well in foil. Bake as directed adding a bit more time to account for the freezing. Cool before using.

Step 9

Whisk the egg yolks and sugar together in a bowl.  Whisk in the flour.

Step 10

Add the milk slowly, whisking well and scraping the corners of the bowl with a rubber spatula to make sure all of the egg yolk mixture is incorporated.

Step 11

Strain the mixture into a saucepan and place over medium heat.

Step 12

Stirring constantly, bring to a boil.  Boil for 1 minute.  Remove from the heat and add the vanilla.  Pour into a storage container, cover the surface with plastic wrap, poke a few holes in it and let it cool.  Refrigerate overnight to chill or it can be frozen for several months. Thaw in the refrigerator where it can be held for 3 or 4 days.

Step 13

When ready to use, whip the cream to medium stiff peaks.   Remove to a bowl.  Place the pastry cream in the mixing bowl and beat with a paddle until smooth.  Fold in the cream.

Step 14

Simple Syrup: Combine the water and corn syrup in a small saucepan. Add the sugar and stir to combine. Bring to a boil oil and boil for 2 minutes. Remove from the heat and cool.

Step 15

Almond Paste: Combine the almond flour and powdered sugar in the processor bowl.  Process briefly to mix well.

Step 16

Combine the simple syrup and almond extract.  Stir well.  Pour over the dry ingredients in the processor in a circle.  Process until it just starts to come together. However, it should come together when a small amount is pinched.  If it is too dry, add more simple syrup very sparingly, just a a teaspoon at a time.  If too wet, add a bit more almond flour.

Step 17

Combine the simple syrup and almond extract.  Stir well.  Pour over the dry ingredients in the processor in a circle.  Process until it appears like sand.  However, it should come together when a small amount is pinched.  If it is too dry, add more simple syrup very sparingly, just a bit at a time.  If too wet, add a bit more almond flour.

Step 18

Pour it our onto a work area and push it together.  Knead it several times; then shape into a log.  Wrap in film and refrigerate for about an hour.

Step 19

This can be made a week ahead and refrigerated or frozen for months well wrapped. Thaw to use.

Step 20

Preheat oven to 350°F. Line a baking sheet with parchment paper.  Set aside.

Step 21

Place everything in the processor bowl and pulse just until crumbly.  Do not overprocess.  You want fairly large crumbs.

Step 22

Spread the crumbs out.  Bake about 7 to 10 minutes or until golden.

Step 23

If they bake up in a sheet, use a fork to pull the dough away to make crumbs while it is still hot.  Cool.  If the crumbs are too big, smash them between your hands.

Step 24

Store in an airtight container at room temperature. for up to a week at room temperature. Try not to eat them.

Step 25

Peel the peaches or blanch them in boiling water to loosen the skin.  My preferred way to place them in boiling water for 30 seconds or more until the skins will slip off. The riper the peach, the easier the skin comes off. Run under cold water and just pull the peels off. For a complete discussion of peaches with photos, please see my post All About Peaches

Step 26

Cut the peaches in about 1/2" pieces. They shoudn't be too thin or they will reduce in size as they cook.

Step 27

Place the all the ingredients except the peaches in a skillet large enough to hold the peaches.Bring to a boil and  boil  for several minutes to reduce the mixture. Add the peaches and continue boiling until the syrup is reduced and the peaches have softened.

Step 28

Cool Completely. This may be made a day or two ahead and stored in the refrigerator.

Step 29

If the tart shell has not been baked, bake it now and cool it completely.

Step 30

After combining the pastry cream with the whipped cream, Spread it into the bottom of the baked tart shell.

Step 31

Spread the caramelized peaches over the pastry cream and top with the brown sugar crumble.

Step 32

If you wish to finish the tart with powdered sugar, cut strips of paper about ¾" wide.  Arrange them on top of the tart. Sprinkle heavily with powdered sugar.  Carefully remove the paper strips.

Step 33

Store the tart in the refrigerator. Allow the tart to sit at room temperature for about 20 to 30 minutes to take the chill off.
