Our grandmothers had an innate sense of simplicity and naturalness: it wasn’t uncommon to see orange peels placed on the stove or in the corner of a wood-burning stove to fill the house with a sweet, warm scent. Much more than just waste, orange zest has long been a full-fledged ingredient in the kitchen. It captures the freshness and vibrancy of the citrus fruit, while offering a multitude of culinary possibilities.
What is zest?
Orange zest is the thin, colored part of the peel, rich in aromatic essential oils. It should not be confused with the pith—the white skin just beneath it—which can impart an unpleasant bitterness. Removing the zest captures the fragrant essence of the orange, enhancing dishes, desserts, or beverages.
Season and Choosing Oranges
Oranges are mainly consumed in winter, from December to April depending on the variety. Since the zest comes into direct contact with any chemical treatments, it is strongly recommended to use organic oranges or oranges labeled “untreated after harvest.” This way, you can fully enjoy their aroma without any health risks.
Nutritional benefits
Rich in antioxidants (flavonoids, carotenoids) and aromatic compounds, orange zest adds a fragrant touch without calories. It aids digestion when steeped and contributes to flavor variety in a balanced diet. Used in small quantities, it helps reduce the need for added sugar in certain desserts by providing natural intensity.
Storage and preparation
The zest is best eaten fresh, but it can also be stored:
- In the refrigerator: grated or in strips, in an airtight container, for 2 to 3 days.
- Dried: spread out on a baking sheet, left to air dry or dried in a very low oven (50°C). Once dry, it can be stored in a sealed jar for several months.
- Candied: soaked in sugar syrup and then dried, it keeps for several weeks and makes a delicious condiment for pastries.
Zest as a condiment
Orange zest can be turned into a homemade condiment:
- Flavored salt: mix dried, finely grated zest with fleur de sel. Perfect for seasoning poultry or a salad.
- Flavored sugar: fresh or dried zest mixed with white or brown sugar. Ideal for flavoring coffee, tea, and pastries.
- Orange powder: Blend the dried zest until you get a fine powder. Sprinkle it on yogurt, pancakes, or fruit salads.
In traditional desserts
Orange zest is a classic in baking:
- Madeleines, brioches, gingerbread: it adds a sunny and delicate note.
- Creams and desserts: crème brûlée, pastry cream, panna cotta… it releases its fragrance when infused in milk or cream.
- Cookies and shortbread: simply adding zest radically changes the flavor.
More creative uses
Beyond desserts, orange zest offers a pleasant surprise:
- In savory dishes: paired with rosemary or thyme, it enhances a poultry marinade, a pork roast, or a fish fillet.
- In sauces: it adds a fresh touch to a vinaigrette, a beurre blanc, or a yogurt sauce.
- In drinks: infused in a syrup, mulled wine, a cocktail, or simply sparkling water.
