14 May Whole Grain Einkorn Rhubarb Galette

The rhubarb season might be my favorite time of the year and I’ve been craving rhubarb ever since the rhubarb season was over last year… That’s how much I love rhubarb, especially rhubarb pies and tarts. My mother often makes  rhubarb crumble during the summer and it’s delicious to eat with a scoop of vanilla ice cream, though today I’m sharing something different with you. I’ve seen them everywhere the last few years but I’ve never tried making a galette before. The great thing about galettes is that they’re so easy to make since you don’t need to fit the crust into a tart tin, just roll out the pastry on a piece of parchment paper, add your filling and fold over the edges, super simple!

The crust is made from 100% whole grain einkorn flour and it tastes amazing. A lot of people who switch from wheat to einkorn do it because of health reasons but also because it tastes so good thanks to it’s nutty and sweet flavor. This crust is flakey, hearty and rustic, just as it should be. I made the galette on a Friday evening for my family and a couple of days later I made the crust again because my mom wanted to bring a rhubarb tart for dessert to some friends. She presented the tart for them without telling them what the crust was made of. She told me that they’d really liked the crust and wondered what made it taste so good. It just shows that these ancient whole grains should get much more attention then they do at the moment because they’re definitely worth it!

I was in a bit of a hurry when I made this rhubarb galette because the sun was already setting when the dough was in the fridge. That’s why some of the pictures are pretty grainy and weird and the reason why I don’t have a photo on the finished baked tart because those photos were too ugly! (If you absolutely must you can have a peek at it HERE…) In the morning I photographed the leftover slices in day light again so that I could show you the finished result and not just pre-baking pictures. Due to the limited time I had, my dough was only in the fridge for about an hour which is a little bit too short. When my mother brought this tart for dessert I made the dough for her on the night before so that it had time to set and cool in the fridge over night. The result was much better and it was so much easier to roll out.

Notes:

  • Einkorn flour is not gluten free though some people (including me) can tolerate einkorn better than wheat. You can read more about it in this post.
  • Remember to make room for the galette in the fridge since it needs to chill for 30 minutes on the tray before baking. 
  • I really recommend making the crust the night before serving. That’ll give it time to properly chill over night and will make it easier to roll out the crust the next day.
  • You can serve the tart with whatever you prefer but I like it with a dollop of turkish/greek yoghurt and a drizzle of honey.
Whole Grain Einkorn Rhubarb Galette

Prep Time: 26 minutes

Cook Time: 45 minutes

Total Time: 2 hours, 30 minutes

Ingredients

  • For the crust:
  • 9 oz (255 g) whole grain einkorn flour
  • 2 tbsp sugar
  • 1/2 tsp salt
  • 6 oz (170 g) unsalted butter, cold and cut into cubes
  • 4 tbsp ice water
  • 1 1/2 tsp apple cider vinegar
  • For the filling:
  • 1 lb / 455 g (6 stalks) of rhubarb
  • 3,5 oz (100 g) sugar
  • 2 tbsp apple juice (or orange juice)
  • 2 tsp corn starch
  • 1 tsp vanilla extract
  • ...
  • heavy cream or milk for brushing
  • raw sugar for sprinkling

Instructions

  1. To make the crust: combine the einkorn flour, sugar and salt in a bowl. Use your fingers to rub half of the butter into the flour until it is the size of peas, then add the rest of the butter and rub until the size of lima beans. Some of the butter will be completely worked into the flour but there should still be a lot of visible pieces of butter in the dough.
  2. Add apple cider vinegar to the ice water. Make a well in the middle of the flour mixture and add a little bit of the ice water. Mix together with your hands or with a wooden spoon until just combined and add more water if necessary (I added all 4 tablespoons). The dough will be very sticky but that’s okay. Flour your hands and the dough, form the dough into a disc and wrap in cling film. Chill dough for at least one hour before using or overnight. The dough should be really firm before rolling out.
  3. Make the filling while the dough is chilling in the fridge. Remove the leaves from the rhubarb and discard. Wash the rhubarb and cut each stalk down the middle lengthwise. Cut into 2 inches / 5 cm long pieces and place in a large bowl with the sugar, apple juice, corn starch and vanilla extract. Toss with your hands to coat and leave to macerate.
  4. Place a piece of parchment paper onto your work surface and dust with flour. Unwrap the chilled dough, dust with flour, and roll out to a 12 to 14” / 30 to 35 cm circle, add as much flour as necessary while rolling out the crust. Place the rhubarb filling on the center of the crust (leave as much of the juice behind as possible), spreading it out and leave a 2” / 5 cm border. Fold the dough towards the middle, over the rhubarb filling. Brush the border of the crust with heavy cream or milk, generously sprinkle raw cane sugar over the crust and filling and top with a few shavings of cold butter.
  5. Transfer the parchment paper to a baking sheet or cookie tray and chill the galette in the fridge for 30 minutes. Bake in an oven preheated to 180°C for 35 to 45 minutes until golden brown and bubbling.

    After reading this I really want to try einkorn. I love anything with a nutty flavour so it sounds amazing to me. Do you just buy it at ordinary supermarkets?
    Love this galette – rhubarb are the best

      Thanks Josefine! I buy whole einkorn berries online and grind my own whole grain flour since I need to have it freshly ground to tolerate it. I know that you can find both light and whole grain einkorn flour online, for example on amazon. 🙂

    I have just started making galettes! They are indeed so much easier than normal tarts, plus they look way more gorgeous imo (as seen here haha)!
