Rhubarb is here! And since it cost me nearly seven bucks, I felt the need to do something slightly elevated. This recipe is adapted from one of my favorite books, How to Bake (Malgieri). The crust reminds me of the sweet, cake-like pastry crusts that Ed's mum makes using self-rising flour. I think my favorite thing about this is the very spring-like color you get from the bright pink rhubarb and the yellow/orange custard. Another nice thing is that poaching the rhubarb cooks it without turning it to mush. Now don't freak - I'm not a "poaching" kind of gal but this was really easy. And it tastes really good.
Rhubarb and Orange Tart
Sweet Dough
2 1/2 c. flour
6 T sugar
1/2 t. baking powder
1/4 t. salt
8 T cold unsalted butter
2 large eggs
milk or cream if needed
Poached Rhubarb
1 1/2 lbs fresh rhubarb
1 c. sugar
2 c. water
Crumb Topping
1 1/4 c. flour
1/2 c. sugar
1/4 t. cinnamon
8 T unsalted butter
Orange Custard
2/3 c. heavy cream
1/4 c. sugar
grated zest of one orange
1 t. vanilla
4 egg yolks
For the Sweet Dough:
Note: This recipe is will make 2 crusts, but only one is needed for this recipe. I'm very paranoid about making too little pastry dough, probably because I'm not the best at rolling it out, so I usually make enough for two crusts and then just use the extra for jam tarts for the kids.
Combine dry ingredients in the food processor and pulse a few times to mix. Cut the butter into 1-tablespoon pieces and add to the work bowl. Pulse repeatedly at 1-second intervals until the mixture is fine and powdery and resembles cornmeal. Add the eggs and pulse 10 more times, until the dough forms a ball. If your dough seems too dry to form a ball, and milk or cream, a tablespoon at a time, until it does. Try not to over-process. Scrap dough onto floured work surface, knead a couple of times to bring together, and shape into a disk. Wrap w/plastic wrap and chill for 1 hour or up to two days.

For the Rhubarb:
If the rhubarb is well developed and tough looking, string it (like you would celery). Cut the stalks into 2-inch lengths. Bring the sugar and water to a boil in a large shallow pan, add the rhubarb, cover, turn off the heat, and allow the rhubarb to cool completely.
For the Crumb Topping:
Combine the dry ingredients in a bowl. Stir the melted butter into the dry ingredients. Allow to stand a minute, then by hand break into coarse crumbs. Set aside.
For the Orange Custard:
Whisk all ingredients together in a mixing bowl until smooth. Set aside.

To assemble the tart, roll out the chilled dough and line a 10-inch (or so) tart pan. Drain the rhubarb (Don't forget to save the syrup for another use - it's really good.) and arrange it in the tart shell. Pour the custard filling over the rhubarb and scatter the crumb topping over the top.
Bake the tart 30-40 minutes, until the filling has set and the crumbs have browned lightly. Cool on a rack.
