Why You Need This Homemade Kumquat Jam in Your Life
Let’s talk about kumquat jam—seriously, why didn’t I make this sooner? I’ve always loved those tiny, bright orange fruits (they look like mini oranges, right?), but I never knew what to do with a whole bag of them. Then last winter, when my throat was scratchy and I was tired of store-bought syrups, I decided to give this jam a shot. Spoiler: It’s a game-changer.
This jam isn’t just tasty—it’s versatile too. Stir a spoonful into warm water for a cozy drink, slather it on toast (trust me, it beats plain butter), or mix it into yogurt for a tangy twist. And the best part? It’s actually soothing for sore throats and coughs. No weird additives, just fresh kumquats and sugar. Perfect for cold and flu season!
What You’ll Need to Make Kumquat Jam
First, let’s gather your ingredients. You don’t need anything fancy—just a few simple things you might already have in your kitchen.
Ingredients List
- 1.35 kg fresh kumquats (that’s about 3 pounds—grab ripe ones that are bright orange and firm)
- 350 g powdered rock sugar (or regular granulated sugar if you don’t have powdered—powdered just dissolves faster)
- A pinch of salt (to bring out the flavor)
- Water (just a tiny bit, if needed later)
Pro tip: Don’t skip the salt! It sounds odd, but it balances the sweetness and makes the kumquats’ tangy flavor pop. You won’t taste it directly, but you’ll notice the difference.
Step-by-Step Guide to Making Kumquat Jam
Let’s get cooking! This recipe is super easy—no fancy canning skills required. Just follow these steps, and you’ll have delicious jam in no time.
Step 1: Prep the Kumquats

Start by rinsing your kumquats. They’re small, so you can just toss them in a colander under cold water. Make sure to get rid of any dirt or debris.
Step 2: Scrub with Salt

Here’s a trick I learned: Add a spoonful of salt to a bowl of warm water, then soak the kumquats for 10 minutes. The salt helps remove any waxy coating (some stores put it on to keep them fresh). After soaking, gently scrub each kumquat with your fingers—you don’t have to be rough, just enough to get the wax off.
Step 3: Drain the Kumquats

Once they’re clean, drain the kumquats well. You don’t want extra water messing up your jam later, so pat them dry with a paper towel if you need to.
Step 4: Slice the Kumquats

Now, slice the kumquats into thin rounds. I like to leave the seeds in (they’re tiny, so you won’t even notice them), but if you’re picky, you can pick them out with a toothpick. Slicing them thin helps the jam cook evenly and get that nice, spreadable texture.
Step 5: Add the Sugar

Pour the sliced kumquats into a big bowl, then add the powdered rock sugar. I use powdered because it mixes into the fruit faster—no more waiting for sugar crystals to dissolve! If you only have granulated, that’s okay too—just stir a little more.
Step 6: Mix Well

Use your hands to mix the kumquats and sugar together. Yeah, your hands—this way you can make sure every slice is coated with sugar. Don’t worry, it’s not messy (and it’s kind of fun!).
Step 7: Refrigerate Overnight

Cover the bowl with plastic wrap and stick it in the fridge. Let it sit overnight—this is the “magic” step! The sugar will draw out all the juicy goodness from the kumquats, so you won’t need to add much (or any) water later.
Step 8: Check the Next Day

Take the bowl out of the fridge the next morning. You’ll see that the kumquats have released a ton of liquid—perfect! That’s all the juice we need for the jam.
Step 9: Cook the Jam

Pour the kumquats and their juice into a pot (I use a non-stick pot to prevent burning). Turn the heat to low—this is key! You don’t want to boil it fast; slow cooking makes the jam thick and flavorful.
Step 10: Stir and Simmer

Stir the jam every few minutes to make sure it doesn’t stick to the bottom. As it cooks, you’ll notice the liquid getting thicker and the kumquats softening. If you want a smoother jam, use a spoon to mash some of the slices—if you like chunks, leave them as is.
Step 11: Test for Doneness

How do you know when it’s ready? Dip a spoon into the jam and let a drop fall back into the pot. If it’s thick and doesn’t run too fast, it’s done. Or put a small plate in the freezer before you start cooking—dab a little jam on the cold plate; if it stays firm, you’re good to go.
Step 12: Store the Jam

Let the jam cool down a little, then pour it into clean jars. Seal the jars tight and store them in the fridge. It’ll last for up to a month—if it even lasts that long!
Final Thoughts: Enjoy Your Homemade Kumquat Jam!
That’s it—your very own kumquat jam! I love how easy this recipe is, and the taste? Tangy, sweet, and just a little zesty. It’s perfect for breakfast, snacks, or when you need a soothing drink for a sore throat.
