Why This Recipe Works

This recipe uses Red Grapefruit which is one of the sweetest varieties of grapefruit and then 1-1/2 cups of fresh-squeezed grapefruit juice is reduced to 3/4 cup to intensify the flavor. Lemon juice is added for a little tartness. The final fruit curd is a tart, creamy, slightly sweet fruit spread that s good as a dessert topping, spread on toast, or as a filling for tarts and cakes.

Grapefruit Curd Ingredients

The basic recipe for this grapefruit curd consists of four ingredients:

• Fresh-Squeezed Grapefruit Juice
• Grapefruit Zest
• Whole Eggs and Egg Yolks
• Unsalted Butter
• Granulated Sugar

Not shown in this picture is the grapefruit zest. Grapefruit zest is the thin outer skin of the grapefruit and contains the oils that carry the flavor of the fruit. Use a microplaner to zest the fruit and be careful to only zest the yellow-pink part not the white bitter pith.

For the best curd, use fresh grapefruit and not bottled grapefuit juice. Since grapefruits are large you'll need 2-3 grapefruits to get 1-1/2 cups of juice

How to Make Tart and Tangy Grapefruit Curd

This recipe is based on my Lemon Curd recipe. But because the flavor of grapefruit is not as intense as lemon juice the recipe starts by reducing 1-1/2 cups of fresh-squeezed grapefruit juice to 3/4 cup.

This step intensifies the flavor and will give the grapefruit a more pronounced flavor. I learned this trick the first time I made it and the thing that I noticed was that the flavor was very distinctive.

After the juice has reduced pour it into a heatproof measuring cup to make sure that you have 3/4 cup and allow it cool to room temperature or until it is barely warm.

Add the grapefruit juice, the lemon juice and half the sugar to the pan and whisk to combine. Taste the mixture, if it is too tart add sugar 1 tablespoon at a time until desired taste is reached.

Next, add the whole eggs and egg yolks and whisk until the eggs are blended in.

Place the saucepan over medium heat and whisk the curd constantly making sure to cover the entire bottom of the pan. Do not walk away from the curd while you are cooking it or it will burn. If you have to walk away for some reason, remove the pan from the heat.

When the curd has thickened and reached the temperature of 185 degrees F strain it through a fine-mesh strainer to remove any solids (little bits of cooked eggs) so it is extra smooth.

Cover the surface with plastic wrap and refrigerate for at least 2 hours before using.

Pro Tips for Making a Delicious Curd

• Cook the curd until it reaches 185 degrees F. Use an instant-read thermometer to check the temperature.
• Don't let the boil or it may curdle and become grainy. If it becomes grainy try straining it with a fine-mesh strainer.
• Use a non-reactive pan (stainless steel or enamel-coated cast-iron). Using a reactive pan such as aluminum will produce a metallic taste in the curd
• Chill the curd immediately to keep bacteria from forming.

How Long Can Fruit Curd be Refrigerated

The grapefruit curd is good in the refrigerator for 2 weeks and can be frozen for up to one year. If you freeze it, allow it to thaw in the refrigerator about 24 hours before you're ready to use it.

Serving Options

• It's great as a topping for pancakes, waffles, ice cream, yogurt, cheesecake, other cakes, and even just plain toast.
• Use it as filling for layer cakes, crepes or sandwich cookies.
• Make my Meyer Lemon Tart and replace the lemon curd with this grapefruit curd.

This Ruby Red Grapefruit Curd is an amazing combination of sweet and sour. I prefer to use Red Grapefruit for the curd because it's sweeter than regular grapefruit and it produces a beautiful sunset colored curd.
