Calamansi curd is a versatile condiment made from the juice of calamansi fruits, which are a type of citrus fruit commonly found in the Philippines. It's a staple in many Filipino households.
Calamansi curd has a unique flavor profile that's both tangy and slightly sweet. This is due to the combination of citric and malic acids present in the calamansi fruit.
To make calamansi curd, the juice of the calamansi fruit is mixed with sugar and water, then cooked until it thickens. The resulting curd can be used as a topping for various dishes.
It's a great way to add a burst of citrus flavor to your meals without the hassle of squeezing fresh calamansi.

Understanding Calamansi
Calamansi is a tiny citrus fruit that's a cross between mandarin oranges and kumquats.
You can find calamansi in the Philippines, China, Borneo, Taiwan, and even in the United States, where it's often sold as an ornamental tree.
These dwarf trees are perfect for small spaces and produce a bountiful harvest of fruit, making them a great choice for home cooks and gardeners.

Calamansi is a popular ingredient in Filipino cuisine and is often used to make a variety of dishes, including calamondin cookies, pie, and juice, also known as Filipino lemonade.
Calamansi has a unique flavor that's a combination of a tangerine's sweetness and a lime's tartness, making it a great addition to many recipes.
My mother has two trees that are heavy with fruit, and I have two small bushes in pots on my back patio, which I'm constantly harvesting for recipes like calamondin fruit curd.
Making the Curd
To make the curd, you'll need to combine the calamondin juice, sugar, and egg yolks in a small saucepan over medium low to medium heat. Whisk to combine and continue stirring constantly until the sugar has dissolved and the mixture has thickened a little.
The key to a smooth curd is to add the butter one tablespoon at a time, whisking until each pat is completely incorporated before adding the next. This ensures the butter is evenly distributed and prevents lumps from forming.

To juice the calamansi, use a small sieve to capture the many seeds – it's a bit time-consuming, but worth it for the best flavor. You'll need to juice about 1 calamansi to get the right amount of juice.
Here's a rough guide to the cooking time: the mixture should thicken within about 5 minutes over medium heat, coating the back of the spoon. Once it's thickened, remove it from the heat and whisk in the butter.
After whisking in the butter, transfer the curd to a storage container and refrigerate for several hours or overnight to allow it to set. This will help the flavors to meld together and the curd to thicken further.

Curd Information
Curd is a type of dairy product that's made by curdling milk with acid or heat.
It's a great source of protein and can be used as a base for various desserts and snacks.
Curd can be made from cow's milk, buffalo milk, or even plant-based milk alternatives.

Calamansi curd, as we're discussing, uses calamansi juice to add a unique flavor and aroma.
The acidity in calamansi helps to create a smooth and creamy texture in the curd.
Curd can be stored in the fridge for up to a week, making it a convenient ingredient to have on hand.
It's also worth noting that curd can be frozen for later use, which helps to preserve its texture and flavor.
