Line a 9x11 pan with parchment paper and preheat the oven to 350°.
Add all the ingredients to the bowl of a stand mixer with the paddle attachment. Blend on low until the mixture is crumbly and relatively combined. Some mildly dry bits are okay as you want to avoid overmixing.
280 g Salted Butter
140 g White Sugar
3 tsp Vanilla
334 g All-Purpose Flour
Turn your shortbread dough out into the pan and pat down to ensure the dough reaches all edges/corners and is relatively compact. Poke the dough with a fork to allow steam to be released while baking.
Bake for 30 minutes or until edges are beginning to brown. At this point, begin assembling your ingredients for the curd, but wait until the 15 minute mark to put your curd on the stove top.
Blood Orange Curd
Add all ingredients to a pot/saucepan.
325 ml Blood Orange Juice
20 ml Lime Juice
280 g White Sugar
215 g Salted Butter
8 Eggs
1 Blood Orange Zest
Bring to a gentle boil slowly while stirring constantly as you don't want the eggs to curdle.
Allow to boil gently for 2-3 minutes or until it begins to slightly thicken.
Remove your Shortbread Crust from the oven and pour the curd on the hot crust.
Return the shortbread pan to the oven and allow to cook for 20-25 minutes, or until the middle looks bubbly.
Remove the pan from the oven and allow to cool on the stovetop. Once it is only slightly warm, transfer the whole pan to the fridge and allow to cool completely.
