Are you as excited about the holidays as I am? I love how the holidays can bring family and friends together. Do you have any special holiday traditions?
Our family has a fun tradition that is centered around cranberries. That probably sounds odd, but we try to develop a new cranberry recipe every year, something that everyone can enjoy.
This is the first year we decided to make syrup out of fresh cranberries. My kids thought a syrup would be fun on gluten-free waffles. Mr. Fearless Dining even suggested making a cranberry ice cream. Personally, I love cranberries in this amazing gluten free banana bread recipe!
I saw this homemade cranberry syrup idea as a delicious way to make cocktails (and mocktails!) for our friends who come to visit :-). Either way, we all win with this easy-to-make cranberry reduction sauce!
If you are entertaining this holiday season, you may want to try serving this Grinch Cocktail too :-).

Cranberries are a symbol of the holidays. These tart little berries are versatile and work with all sorts of recipes, from sauces to baked foods! Their tart flavor works beautifully with sparkly 7UP.
You are going to love this sparkling cranberry cocktail for holiday entertaining! You can also use the cranberry syrup to make mocktails. Follow the same recipe and skip the rum.

Given the tartness of this simple cranberry syrup, I chose 7UP to add sweetness to this cranberry rum cocktail recipe. The flavor of 7UP works well in so many cocktail recipes. Try pairing 7UP with liquors like:
- Bourbon
- Vodka
- Amaretto
- Gin
- Rum
Are you ready to see how easy this sparkling cranberry rum and 7UP cocktail is to make?

How To Make This Cranberry Rum Cocktail:
Step 1: Wash the cranberries and remove any that are not fresh. Add the fresh cranberries, sugar, cinnamon, vanilla, 7UP, and water to a pot.
Step 2: Cook the cranberry mixture on medium heat until the cranberries pop. (You will actually hear them pop, it is really fun!)
Step 3: Use a spoon to mash the cranberries up against the pot's side.
Step 4: Allow the cranberry mixture to simmer for another 15 minutes. The sauce will be thick with the cranberry chunks.

Step 5: Use a mesh strainer to strain out the cranberry pulp. I kept a container underneath to capture all the delicious syrup. You should end up with a bowl of syrup and a bowl of cranberry pulp.
🔑 Sandi says: The cranberry pulp is delicious and can be used in recipes like gluten-free cranberry muffins...or you can make a chutney out of it and serve it with chicken or pork!

Add the cranberry simple syrup into a glass. For a cocktail, add rum and 7UP. For a mocktail, skip the rum.
We had fun making this sparkling cranberry cocktail in different glasses to decide which made the drink look fancy for entertaining. What do you think? You may also have fun making this Cranberry Moscow Mule.

Rum, cranberries and sparkling 7UP. Sounds like a tradition I could get behind. I love all of the ways that you could serve this. It is beautiful in a coupe and a real showstopper in a highball.
Sandi Gaertner
Thank you so much Leigh...I think you can do a lot with the homemade cranberry syrup. I love the highball idea 🙂
Lori
How far in advance can I make the simple syrup. Because I’m entertaining a lot for people.
Sandi Gaertner
Hi Lori, I stored it for 5 days without issue. I am sure you could freeze the syrup and then thaw it when you need it. Take care and have a great holiday party 🙂
Angela
Hi! What kind of rum do I use?
Sandi Gaertner
Hi Angela, the rum doesn't really matter. I would use any clear rum. Do not use spiced or dark rum. Have a great day!
Hilary Duesenberg
Hi Sandy!
This may be obvious, but when making the cranberry syrup do I add the 7up and rum, and then add more 7up and rum later?
Sandi Gaertner
Hi Hilary, you are right, it can be confusing. I add 7Up while cooking. The rum is poured over the ice with the completed syrup. I add more 7Up on top for a fizz. I hope that helps. Have a wonderful holiday!
