Kumquat

Citrus japonica

fruit

Kumquat is the small oblong citrus you eat skin and all: the sweet tender peel balances the sour-tart pulp inside for a flavor unlike any other citrus, often eaten whole as a sweet-sour candy. The compact tree (4 to 8 ft) is naturally cold-hardier than most citrus and one of the most container-friendly fruits for cold-climate gardeners.

🌾 Harvest & storage

Kumquats ripen from late autumn through early spring; pick when the fruit turns bright orange and easily separates from the stem with a gentle twist. The signature way to eat fresh: pop the whole fruit in your mouth, bite, and savor the contrast of sweet peel and sour flesh. Pickle whole fruit in salt and lemon (Moroccan style), candy in sugar syrup, or chop into salads and marmalade.

🥗 Nutrition & benefits

About 71 calories per 100 g with 6.5 g fiber, 43.9 mg vitamin C (73 percent of DV), and 186 mg potassium. Because you eat the whole fruit, kumquats deliver dramatically more fiber and peel-oils (citrus essential oils linked to antimicrobial activity) than other citrus.
