Kumquat Marmalade Recipe

I can still recall the first time I tried kumquat marmalade Recipe. It was one spring morning at a nearby farmers market, and when I had my first taste, one spoonful was all it took for me to fall in love. It was sweet and tangy, and a bit bitter too, in that citrus way that only citrus can be. 

After experiencing that, I just needed to learn how to make it myself. After some tweaking, I’ve gotten to the point where I have my own Kumquat Marmalade Recipe, and honestly, it is one of my top preserves, especially during kumquat season.

A Little Backstory Behind This Citrus Star

Kumquats are native to Asia but can easily be found growing in sunny backyard gardens all throughout California and Florida. They are basically mini oranges; however, you eat the whole fruit (the peel and the flesh). 

This optional peel adds a hint of sweetness when you bite into it, while the pulp provides a fresh and tangy kick. Marmalade is often described as a spread or condiment made from Seville oranges…but you can make kumquat marmalade too! 

There’s no need to worry about a special pectin. The natural citrus does all the work. The recipe I’ll share with you is a very simple kumquat marmalade recipe based on traditional preserving sessions, but I have made it easier for the everyday home cook.

Why I Keep Coming Back to This Recipe

What I really enjoy about this recipe is the ability to make something that tastes so gourmet with just a few ingredients. It has the best combination of flavors being sweet, tart, and bitter all at the same time. You can eat it on toast, stir it into your yogurt, or spoon it over grilled chicken or a cheese board. 

Additionally, making this kumquat marmalade recipe fills your home with a warm, citrusy aroma. It always feels like doing something rustic and wholesome (and I mean that in a good way!).

Equipment You’ll Need

Nothing fancy here! Just some kitchen basics:

• Sharp knife or mandoline
  
• Large heavy-bottomed saucepan or Dutch oven
  
• Wooden spoon or silicone spatula
  
• Fine-mesh strainer (optional, if you prefer less pulp)
  
• Sterilized glass jars with lids
  

Secret Tips to Make It Perfect

• Soak the sliced kumquats overnight in water. This softens the peels and reduces bitterness.
  
• Slice thinly and remove seeds as you go—kumquats are tiny, but those seeds can add too much bitterness.
  
• Use a candy thermometer if you’re unsure about the setting point. You’re looking for 220°F (105°C).
  
• Stir often—this prevents sticking and ensures even cooking.
  

Common Mistakes to Avoid

• Don’t rush the simmering process. Let it gently bubble so the flavors can deepen and thicken naturally.
  
• Skipping the soak can make the marmalade harsh and overly bitter.
  
• Overcooking will result in a sticky, taffy-like texture instead of a spreadable jam.
  

Ingredient Swaps & Customizations

Want to mix things up?

• Add fresh ginger for a warming bite.
  
• Vanilla bean or extract for a mellow, aromatic twist.
  
• Replace some sugar with honey (but only up to 25% to keep the consistency right).
  
• Use a mix of kumquats and oranges or Meyer lemons for a softer flavor.

FAQs About Kumquat Marmalade

Q: Do I have to use sugar, or can I make it sugar-free?
A: For proper preservation and consistency, sugar is essential. You can reduce it slightly, but going sugar-free isn’t recommended unless you’re refrigerating and eating it quickly.

Q: Can I freeze the marmalade instead of canning it?
A: Yes! Store in freezer-safe containers. Just leave space at the top since it expands.

Q: How long does it last?
A: Sealed jars can last up to a year in a cool pantry. Once opened, refrigerate and use within 1 month.

Q: Can I double the batch?
A: Yes, but larger batches may take longer to cook down. Stir often and check the consistency carefully.
