- Servings: 8
1 sweet tart crust, unbaked
1 1/4 lbs rhubarb, washed and sliced in 1/2" pieces (or long thin batons if you want a more dramatic presentation)
1/2 cup + 2 Tbsp sugar, separated
2 Tbsp flour
1 pinch salt
1 cup half and half
1/2 tsp vanilla
In a large bowl, toss the rhubarb with 2 Tbsp of the sugar until it's evenly coated. Transfer the sugary rhubarb to a colander over the bowl, and let sit at least 2 hours to allow liquid to drip out. Overnight is fine too.
Preheat the oven to 375 degrees. Roll out the crust and fit it into a 9" tart pan, prick a few times with a fork, and place in the refrigerator to chill while the oven is preheating.
Whisk together the remaining 1/2 cup sugar with the flour and salt. Add a bit of half and half, whisking until it's a well-combined sludge. Add the remaining half and half, eggs, and vanilla, whisking until just combined.
Remove the crust from the refrigerator. Press on the rhubarb to expel any last bits of liquid, and scatter evenly (more or less) over the crust. Give the custard another whisk to re-mix, and pour gently over the rhubarb. Place in the oven.
Bake until the custard no longer jiggles in the center and is just beginning to brown, about 30-45 minutes. The filling will puff dramatically (but will settle back down as it cools). Remove from the oven and let cool a bit before serving.
