Soon after Elizabeth mentioned them, we spotted cara cara oranges at our local grocery. We ate a few for afternoon snacks, but then our thoughts quickly turned to dessert. Wouldn't this sweet citrus make a great jam curd? Why, yes it would!
We'd hoped the curd would end up as pink as the fruit, but alas, it seems the pink color comes from the flesh of the orange and not the juice. All the same, we love the sunny orange hue that we did get!
If you can't find cara cara oranges in your grocery, feel free to substitute regular navel oranges - or any other seasonal citrus, for that matter! Simmering the juice down helps to concentrate delicate citrus flavors and makes the resulting curd more intensely flavored.
Cara Cara Orange Curd Makes about 1 cup
1/2 - 3/4 cups orange juice from 2 oranges zest from one orange 1 tablespoon lemon juice 1 large egg 2 large yolks 1/4 cup granulated sugar 4 tablespoons unsalted butter, cut into chunks and softened pinch of salt
Pour the orange juice into a small sauce pan over medium-high heat. Bring the juice to a rapid simmer and let it reduce down to approximately 1/4 cup. This should take 2-4 minutes.
Transfer the orange juice to a measuring cup to cool. Stir in the zest and lemon juice.
In a separate bowl, whisk together the egg, yolks, and sugar. When the orange juice has cooled to room temperature, whisk it into the egg mixture in a steady stream.
Place a clean bowl with a strainer over the top next to the stove.
Pour the egg and juice mixture back into your small sauce pan and set it over medium heat. Stir slowly but constantly until the mixture has thickened to a pudding-like consistency - about 6-8 minutes or until the mixture is 180°.
Strain the mixture into the clean bowl to remove the zest and any bits of cooked egg. (Alternatively, you can leave the zest in the curd for a chunkier texture.) Stir in the butter and the pinch of salt while the curd is still warm.
Store the curd in a clean jar with a lid. It will keep refrigerated for about a week.
