Blueberry Lemon Curd Bars

Tart but sweet in the most special way that only comes from combining blueberries and lemon. The curd is smooth and the shortbread crust is crumbly, thick and lemony!

 

 

 

Over the past week I’ve made ALL the curds. Sometimes I get obsessed with baking something and I’ll make it sixteen times in a row (every time just a little different to satisfy my curiosity… what would happen IF?…). I remember winter 2018, I made every marshmallow flavor possible. Recently I’ve been having fun with meringues (see apple cider and cara cara) and challah/babka/brioches (you saw the result of some of that here! So in one morning I made four different kinds (see pic below):

 

 

Lemon curd, orange curd, cranberry curd…and blueberry curd!

Ina’s was, as it is every time I make it, the most delicious sauce ever and if you haven’t made it yet, your life isn’t complete until you do. I’ve made David’s before and used it between cake layers and swirled it around this tart. Melissa’s Orange curd was the one I adapted to make this beaut. So the only new guy in the house was the blueberry – and my oh my is it WONDERFUL. Other berry curd recipes seem to just barely taste like the actual berry, or not have enough of a tart bite to them. Liren’s recipe was beautifully silky, tasted like blueberries and was even tart from the addition of lemon.

I’d seen these lemon bars via Melissa Clark awhile ago, and planned to make them with the bags of meyer lemons I had on hand. But then I imagined the blueberry curd on top and… ooof. Wouldn’t that be a recipe worth developing?

So here we are. I used Liren’s method to make the juice (cooking blueberries in lemon juice) and then adjusted Clark’s recipe . AND GUYS, THESE ARE DIVINE!!!

The bars are both tart from the lemons and sweet from the blueberries. Somehow you get both without one taste overpowering the other. The crust (nice and thiccc) is a wonderful lemony shortbread vehicle. I’m obsessed!

 

Notes and tips to make Blueberry Lemon Bars

  • To ensure your curd sets after baking, make sure to bring the curd to a boil and then let it boil for just 30-45 seconds afterwards.
  • I didn’t add zest to keep a smooth texture but if you would like to add some to the curd, go for it! Definitely don’t skip it in the crust though – it’s amazing.
  • These are easiest to cut once they have been in the freezer for a bit. They even taste good straight from the freezer because the curd doesn’t freeze.
  • If you’d like to, you can use a 50/50 mixture of butter and olive oil in the curd instead of all butter.

Blueberry curd bars on a crumbly lemon shortbread.

By:

Ingredients
  • Thick Lemon Shortbread Crust
  • 1 ¼ cups all-purpose flour
  • ¼ cup granulated sugar
  • 3 tablespoons powdered sugar
  • Zest of 1 lemon
  • ¼ teaspoon fine sea salt
  • 10 tablespoons unsalted butter, cut into cubes
  • Blueberry Curd Filling
  • 2 cups fresh blueberries
  • ½ cup freshly squeezed lemon juice
  • ¼ teaspoon fine sea salt
  • 1 cup sugar
  • 2 eggs
  • 3 egg yolks
  • ½ tablespoon tapioca starch (or cornstarch)
  • 8 tablespoons unsalted butter
Directions
  • Step 1 Preheat oven to 325 F. Line an 8×8 inch square pan with parchment paper to form a sling on each side.
  • Step 2 In a large bowl add all the dry ingredients for the crust and whisk together.
  • Step 3 Using a pastry knife, cut in the butter until it becomes pea sized. Use your hands to smooth the rest of the butter into the dough until crumbly and all flour is coated (alternatively, pulse all ingredients in a food processor).
  • Step 4 Press crust dough into the bottom of the pan and bake it for 30 minutes, until crust is golden.
  • Step 5 While crust is baking, make the filling:
  • Step 6 In a pot, cook blueberries and lemon juice on medium until berries soften. Use the back of a wooden spoon to press the blueberries to release their juices.
  • Step 7 Press the blueberry mix through a fine mesh sieve, scraping the bottom of the sieve to get all the juice. You’ll need ¾ cup of juice to make the curd (no more).
  • Step 8 Return the blueberry juice to the pot, with the heat off. Once it is cool enough, add the salt, sugar, eggs, yolks, and starch. Whisk to combine.
  • Step 9 Turn the heat on and add the butter, whisking frequently as butter melts.
  • Step 10 The curd will thicken after about 5 minutes or more, stir it often as it thickens. Let it come to a boil and then sit for about 30 seconds.
  • Step 11 Over a bowl place a fine mesh sieve. Pour the curd through the sieve, pressing down to get as much out as possible.
  • Step 12 When the crust is golden, remove from oven and pour in the curd. Return to the oven.
  • Step 13 Bake for 10-15 minutes until the curd is set.
  • Step 14 Let the bars cool at room temperature and then place in the fridge.
