What Is Ginger?
Ginger (Zingiber officinale) is the underground rhizome of a tropical plant in the ginger family. It originated in Southeast Asia and has been used for thousands of years as both a spice and a traditional remedy. Its sharp, mildly peppery, refreshing aroma comes from a compound called gingerol.
In cooking, it comes in two main forms: fresh ginger root, which is fibrous and juicy, and ground ginger, which is dried and powdered. Fresh ginger has a brighter, sharper flavor, while ground ginger tastes warmer and more concentrated; they are not directly interchangeable and should be treated differently in recipes.
Ginger Nutrition Facts
Fresh ginger is a low-calorie spice; 100 grams contain about 80 kcal, 17.8 g of carbohydrates, and 2 g of fiber. It contains potassium, magnesium, and a small amount of vitamin C. However, because people usually consume only a few grams in everyday use, its main value comes from its aromatic compounds rather than its macronutrients.
What Are the Benefits of Ginger?
For centuries, ginger has been used in traditional cooking to ease digestion and soothe the stomach. Scientific studies suggest that ginger may help relieve nausea. Research into the antioxidant properties of gingerol is ongoing.
This information is general; ginger is a food and spice, not a substitute for medical treatment. People who take medication regularly and people who are pregnant are advised to consult a health professional before consuming large amounts.
How to Choose Ginger
When buying fresh ginger, look for a firm, heavy rhizome with glossy skin. A good-quality piece snaps crisply and has a strong aroma.
- The skin should be thin, taut, and smooth; wrinkled skin indicates that the rhizome has dried out.
- Rhizomes that feel heavy and plump in your hand are juicier.
- Do not buy rhizomes that are soft, moldy, or sprouting.
How to Store Ginger
Fresh ginger keeps for 3–4 weeks in the refrigerator crisper when wrapped in a paper towel. For longer storage, freeze it unpeeled; grate the frozen rhizome directly into the pot. Ground ginger keeps its aroma for a long time in a tightly closed jar stored in a cool, dark cupboard.
- Fresh ginger: wrapped in paper, refrigerated for 3–4 weeks.
- Freezer: unpeeled, for months; ideal for grating.
- Ground ginger: up to 1 year in a closed jar kept away from light.
Using Ginger in the Kitchen
Ginger works in both savory and sweet dishes: it adds depth to meat and chicken marinades, a warming bite to soups, and spicy warmth to cakes and cookies. It is essential in East Asian stir-fries, curry blends, and pickles.
How to Make Ginger Tea
Add 2–3 thin slices of fresh ginger to a glass of boiling water and steep for 5–10 minutes. Add a slice of lemon and, if desired, one 5 ml measure of honey before drinking. In winter, it is enjoyed as a refreshing, warming drink.
Fresh Ginger in Cooking
When adding fresh ginger to a stir-fry, add it near the end and briefly sauté it with the garlic; prolonged cooking dulls its aroma. Grated ginger can also be added raw to salad dressings and marinades.
What Recipes Use Ginger?
Popular uses include ginger chicken stir-fry, ginger-carrot soup, spiced cake, and ginger lemonade. Ground ginger is common in ginger cookies and winter desserts, while fresh ginger features in East Asian dishes and teas.
