Grapefruit Syrup Recipe

Grapefruit syrup is incredibly versatile and can enhance a wide range of foods and beverages. It can be stirred into sparkling water, herbal teas, or over ice for a refreshing drink. Follow my recipe to make a perfect batch!

There is something almost magical about grapefruit. It is tart yet sweet, bold yet refreshing, with a bitter edge that adds sophistication to anything it touches. While oranges and lemons tend to steal the spotlight, grapefruit quietly brings a complexity that makes recipes stand out. One of the best ways to capture that essence is by making grapefruit syrup at home.

This syrup is not just for sweetening. It is versatile, working beautifully in sparkling water, drizzled over pancakes, folded into yogurt, added to dressings, or even spooned over fruit salads. It transforms everyday dishes into something that feels a little more special. If you generally love citrus, you could try my lemon or lime syrup recipes for a slightly different twist.

Why you need to make your own grapefruit syrup

Grapefruit hits that sweet spot between tangy and bitter, giving depth where simple lemon or orange syrup might feel too plain.

Winter and early spring are peak grapefruit seasons, making it an ideal time to capture their juiciness if you are looking to store larger quantities. Though they tend to be available year-round.

Store-bought syrups are usually flat, overly sweet and full of articifial colors and preservatives. A homemade version allows you to control the balance, adjusting sugar to taste.

Ingredients you’ll need

• Red grapefruit (1 large one or 2 smaller ones)

• Sugar

• Water

• Optional: a small piece of grapefruit peel with the white pith removed for extra zestiness

How to make grapefruit syrup at home

1. Prepare the grapefruit: Wash the grapefruit thoroughly. Cut it in half and squeeze out all the juice. You should end up with around 1 cup of juice. If it is a little less, top it up with water. If you want a more intense citrus aroma, peel a thin strip of zest without the bitter white pith.

2. Cook the syrup: In a saucepan, combine the sugar and water. Stir over medium heat until the sugar dissolves. Add the grapefruit juice and zest. Simmer gently for 20 minutes, letting the flavors meld together then remove it from the heat and let it cool completely.

3. Strain and store: Strain the syrup through a fine sieve to remove pulp and zest. Pour into a clean glass jar or bottle. Store in the fridge for up to 2 weeks.

Tips and variations

You can easily adapt grapefruit syrup to suit different flavors and occasions. For an herbal twist, try adding rosemary, thyme, or basil while simmering. If you want a warming, spiced version, toss in a cinnamon stick or a star anise. For a softer sweetness, you can substitute honey for sugar, though this will slightly alter the shelf life. These small adjustments allow you to create a syrup that is uniquely tailored to your taste and the dishes or drinks you plan to use it in.
