How to Make Lemon Raspberry Bars

Ingredients

2 cups raspberries (250 grams) (fresh or frozen)
2 1/4 cups all-purpose flour (281 grams)
1/2 cup granulated sugar (100 grams)
1 tablespoon corn starch
1/4 teaspoon salt
1 cup unsalted butter (226 grams) (melted)
1 1/2 cups granulated sugar (300 grams)
1/3 cup corn starch (40 grams)
6 large eggs
1/4 cup reduced raspberry puree (60 ml) (reduced from 2 cups raspberries – see step 1 of the directions)
3/4 cup lemon juice (180 ml) (freshly squeezed)

Directions

Raspberry Puree: In a saucepan, cook the raspberries over medium heat until they break down. Strain the mixture to remove the seeds, and reduce the liquid until you have about 1/4 cup of the puree.
Shortbread Base: Preheat your oven to 350°F (175°C). In a large bowl, mix 2 1/4 cups flour, 1/2 cup sugar, 1 tablespoon corn starch, and 1/4 teaspoon salt. Add the melted butter and mix until crumbly. Press this mixture evenly into the bottom of a baking dish. Bake for 20-25 minutes until lightly golden.
Lemon Raspberry Layer: In a separate bowl, whisk together the 1 1/2 cups sugar, 1/3 cup corn starch, and eggs until smooth. Stir in the reduced raspberry puree and the lemon juice. Pour this mixture over the baked shortbread layer.
Bake: Return the dish to the oven and bake for an additional 25-30 minutes, or until the top is set. Let cool completely before cutting into bars.
