What Exactly is a Kumquat?

Also known by its Cantonese name, which means 'golden orange,' a kumquat is a small, oval or round citrus fruit. While it resembles a miniature orange in appearance, its flavor profile and structure are distinctly different. The most notable characteristic is the edible skin, which is sweet, fragrant, and lacks the bitter pith found in larger citrus fruits. The juicy flesh inside, however, is intensely tart. When eaten together, the combination of the sweet peel and sour pulp creates a delightful and unique sweet-tart sensation.

Common Kumquat Varieties

Kumquats come in several varieties, each with slightly different characteristics in terms of shape, flavor, and size. While all are small, some varieties are more popular than others, especially in different parts of the world:

• Nagami Kumquat: This is the most common variety found in the United States and is known for its distinct oval shape. It has a characteristically tart interior and is often used for making marmalade and other preserves.
• Meiwa Kumquat: The Meiwa is a round kumquat that is generally sweeter and less seedy than the Nagami. Its sweet, mild flavor makes it particularly popular for eating fresh.
• Centennial Variegated Kumquat: This unique variety features beautiful green and yellow variegated leaves and striped fruit. The fruit itself is larger than typical kumquats and offers an acidic, juicy, and tart flavor profile.
• Fukushu Kumquat: Also known as the 'Large Round Kumquat,' this hybrid with mandarin is larger and has a smoother rind, making it excellent for candying.

How to Eat and Prepare Kumquats

Enjoying a kumquat is surprisingly simple. Because the entire fruit is edible, preparation is minimal. Here’s a simple guide:

1. Wash Thoroughly: As with any produce, wash the fruit well under cool running water before eating.
2. Roll for Flavor: To enhance the flavor, gently roll the fruit between your fingers. This releases the essential oils in the peel, which intensifies the sweet aroma.
3. Eat Whole: Pop the whole kumquat into your mouth and bite. The initial sweetness from the peel is followed by the sour burst of the flesh, creating a complex and balanced taste. The seeds are edible but can be removed if you prefer.
4. Cooking and Baking: For cooking, kumquats can be sliced and added to salads, roasted with meats, or used to create delicious marmalades and chutneys. The seeds contain pectin, which helps thicken preserves naturally.
