Orange
Oranges add sweet citrus notes that brighten dishes.
Oranges are citrus fruit first grown in southern China, now one of the most popular fruits on the planet. They taste sweet and juicy with a gentle acid backbone, and the peel holds a powerful, fresh citrus perfume with a soft floral edge.
Cooks use every part. The juice sharpens glazes, marinades and dressings, the segments add juicy pops to salads, and the zest brings big aroma to cakes, chocolate and braises without adding liquid. From duck à l'orange to carnitas to a chocolate orange torte, it moves easily between sweet and savoury.

Season: Winter is peak season in the Northern Hemisphere, from roughly December to April, with blood oranges arriving mid-winter. Imported oranges keep them available year-round.
Nutrition: Oranges are a well-known source of vitamin C and provide some fibre when eaten whole.
Storage: Oranges keep about a week at room temperature and 3–4 weeks in the fridge crisper drawer, loose rather than sealed in plastic. Watch for soft spots, white or green mould, or a fermented smell. Juice freezes well in ice-cube trays, and zest can be frozen in a small bag for months.

How to use orange
The zest holds the aroma
The peel is loaded with limonene oil, which is where most of the orange smell comes from. Grate only the colored part.
Citrus Balance
Acid levels balance flavor, while segments add juiciness.
The science of orange
- Most of an orange's smell lives in tiny oil glands in the coloured outer peel. The main compound is limonene, which is why zest adds far more aroma than juice.
- The white pith under the zest is bitter because it contains naringin and related flavonoids. Zest lightly and trim pith from segments to keep the flavour sweet.
- Orange juice is mostly citric acid and sugar. Reduced in a pan, the water evaporates and the sugars concentrate into a sticky, glossy glaze that browns quickly.
- Juice exposed to heat or air loses its fresh notes fast because the aroma compounds are volatile. Add fresh juice or zest at the end of cooking for the brightest flavour.
- Citrus peel is rich in pectin, the gelling fibre that lets marmalade set. Simmering the peel with sugar and acid releases it.
How to choose orange
Choose oranges that feel heavy for their size, which means plenty of juice. The skin should be firm and smooth-ish, without soft, mouldy or sunken patches. A little green on the skin is fine and doesn't mean the fruit is unripe.

Orange: questions
How do you zest an orange?
Use a fine grater or microplane and grate only the bright orange layer, turning the fruit as you go. Stop when you see white pith, which is bitter. Zest before you juice, as it is much harder afterwards.
Why does my orange dish taste bitter?
Usually the pith got in, either from zesting too deeply or using whole peel. Long cooking can also dull the fresh notes. Add fresh zest or juice at the end to brighten it.

Freeze the juice and zest rather than whole fruit. Juice keeps for months in ice-cube trays, and zest freezes well in a sealed bag. Whole frozen oranges turn soft and watery.
