At Sweet C’s, I add lots of tips in all of my recipes – because I am a home cook without any formal training, and I find I am more confident making dishes when I understand why it works, and what each ingredient means to the flavor of a recipe. My goal is for even the most beginner home cook to feel empowered in the kitchen.

How to Make Mulled Simple Syrup

Mulling spices are delicious in Mulled Beer, Traditional French Vin Chaud, The Best Mulled Cider Ever, Ginger Mulled White Wine – but also delicious to enhance flavors in baked goods like Easy Caramel Apple Spice Cake, and Israeli Cardamom Coffee!

Simple syrup is a simple mixture of sugar and water – boiled so the sugar dissolves and is not grainy – this syrup is a delicious, easy way to sweeten drinks, add flavor to cocktails and mocktails, and even flavor baked recipes!

Making any flavor simple syrup is super-simple – it basically just includes boiling and stirring water.

Ingredients to Make Mulled Simple Syrup

To make this recipe, we need the following ingredients:

• 1 cup water – This is the foundation of the syrup, helping dissolve the sugar and pull all the cozy flavors out of the spices.
• 1 cup sugar – Sweetens everything up and gives the syrup that smooth, syrupy body while balancing the stronger spices.
• ¼ teaspoon ginger – Adds a bright, zippy heat that keeps the syrup lively instead of overly sweet.
• ¼ teaspoon cinnamon – Brings classic holiday warmth and that comforting mulled-spice sweetness.
• ¼ teaspoon nutmeg – Gives a soft, nutty depth that makes the syrup taste richer and more bakery-warm.
• ¼ teaspoon clove – Adds bold, unmistakable spice; just a touch gives the syrup that traditional mulled flavor.
• 1–2 cardamom pods – Lends a citrusy, floral lift that keeps the syrup from feeling too heavy.
• 1 teaspoon juniper berries – Adds crisp, piney brightness—just enough to make the syrup feel wintery and fresh.
• ¼ vanilla bean – Brings smooth, creamy sweetness that softens the sharper spices and rounds everything out.
• 3–4 star anise pods – Adds a sweet, licorice-like aroma that ties the whole mulled profile together beautifully.

Steps to Make Mulled Simple Syrup

Once you’ve gathered your ingredients, we will use the following process:

We’re sharing our best tips to make perfect simple syrup below!

Toast your spices first – Warming the spices in the pot for a minute before adding water and sugar wakes up their oils and gives the syrup a deeper, richer flavor.

Simmer gently (don’t boil hard) – A soft simmer extracts flavor without turning the spices bitter or reducing the syrup too much.

Don’t walk away from the pot – Spiced syrups can go from perfect to overpowering quickly, so keep an eye on it while it simmers.

Taste as you go – If you love strong spice, let it steep a little longer; if you prefer something lighter, strain earlier.

Crack the cardamom pods – Lightly crushing them with the back of a spoon helps release their floral fragrance without making the syrup cloudy.

Use whole spices when possible – They infuse cleaner flavor and are much easier to strain out than ground spices.

Strain well for a smooth syrup – Pour it through a fine mesh strainer, and if you want restaurant-level clarity, line the strainer with cheesecloth.

Add citrus peel for extra brightness – A strip or two of orange or lemon peel can make the syrup smell even more festive (just avoid the bitter white pith).

Let it cool completely before bottling – This helps the flavors settle and prevents condensation from watering down your syrup.

Shake before using – The spices can settle at the bottom, so give it a quick shake to wake the flavors back up.

Store it in the fridge – It keeps about two weeks as written—or longer if you make a richer syrup (more sugar) or add a splash of alcohol.

Add more sugar – Add more or less flavor as needed – this recipe is meant to work as a base for your simple syrup. If you’d like a very strong spiced flavor, double the amounts of spices called for in the recipe.

Add more water – For a lighter spiced flavor, double the water and sugar.

Dried fruit peels can be added for more festive flavor, and peppercorns can be added for a bit of a kick. Dried cranberries (not sweetened), orange peel, grapefruit peel, or apples are all traditional in mulling spices.

Use pre-mixed spices – Pre-made mulling spices can be used in this recipe – use 2 teaspoons.

Mulling spices are a combination of cinnamon, cloves, allspice, and nutmeg; and sometimes star anise, and cardamom – our version also includes ginger and juniper berries, as well as vanilla.

Simle syrup is a suspension of sugar in water that is generally made of equal parts sugar and water, and can be flavored any way you’d like! Simple syrup is a great way to flavor drinks without watering it down.

• In a small pan, combine water, sugar, and spices.
• Bring to a boil, stirring constantly, to dissolve sugar.
• When sugar is fully dissolved, remove from stove and let cool.
• Syrup can be strained if you’d like to remove any herbs that don’t dissolve completely.
• Store in airtight container in the refrigerator for up to two weeks.
