You NEED to try my homemade Grapefruit Syrup this summer; it is refreshing, citrusy, and super addicting!
All you need is two simple ingredients to make homemade Grapefruit Syrup, grapefruit and sugar. Enjoy it in the morning with hot water, and make it with tequila at night for the PERFECT summer cocktail.
Make Grapefruit Syrup in bulk as it can last in the fridge for up to 1 month. Trust me; you don’t want to miss out on this DELICIOUS summer drink!

I am not joking when I say I’ve been drinking my homemade Grapefruit Syrup EVERY SINGLE DAY for the past few weeks.
In fact, right now, as I am writing this blog post, I am sipping on my grapefruit cocktail. Whenever grapefruit is on sale, I will buy it in bulk, put on my favorite show, and make myself jars of syrup.
Not going to lie, it is time-consuming, but it is so worth it. After a while, it becomes even therapeutic to peel the grapefruit.
I love my homemade Grapefruit Syrup because you get the best of both worlds, the chunky fruits, and citrusy sweet syrup.
Grapefruit seeds are bitter; that is why it is crucial to ensure that no seeds are inside the syrup. There are two ways to peeling; I like to use my hands to peel off the skin and a mini toothpick to flick off the seeds.
You can alternately also use a knife to cut out the fruits to save time. Whatever is the easiest method for you to ensure that only the actual fruit is in the syrup, not the white parts of the skin or the seeds.
PRO TIP: when making Grapefruit Syrup, DO NOT THROW AWAY THE PEEL.
Another reason why I love making homemade grapefruit syrup is after I will use the peels as a natural simmer pot recipe so that the house will smell super clean and refreshing!
In a large pot, add in all the grapefruit peels and whatever herbs of your choice. I like to use rosemary and some mint from our balcony garden. Fill the large pot with water, bring it to a simmer, turn the heat to low and let it simmer for 2-3 hours.
The simmer pot will eliminate all the food smell in your kitchen, and your house will smell AMAZING.

I am a HUGE fan of making homemade syrup.
I also have a Lemon Honey Syrup, Strawberry Syrup, and Kumquat syrup recipe in my blog. Depending on the season, I will buy fruits in bulk, turn them into syrup for easy drinks, and prevent the fruit from going bad.
Blueberry season is just around the corner, so stay tuned so I make my famous Blue Berry syrup that will BLOW YOUR MIND!
