- Can I use carton orange juice?
- In an emergency, yes, but choose 100% unsweetened. However, the essential oils of fresh fruit will be missing.
- The sauce turned bitter. Why?
- Likely the white pith (albedo) of the orange got in when grating, or the rosemary burnt in the butter. Always zest only the orange part!
- How long does it keep?
- In the fridge, in a clean jar, it can be consumed for up to 1 week.
Rosemary and Orange Sauce
Pairing citrus fruits with herbs is one of the oldest kitchen tricks to freshen up heavy meat dishes. In this sauce, the sunny sweetness of orange meets the earthy, resinous character of rosemary. This isn't a creamy, heavy dressing, but a bright, translucent 'jus'-style sauce that coats the meat without overpowering its flavour. Perfect for duck, but surprisingly good with grilled cheese too.

Instructions
1
✓
Thoroughly wash the orange in hot water, then grate the zest. Squeeze the juice. Chop the rosemary as finely as possible.
Tip: Hot water washing removes the wax layer on the skin, giving a cleaner flavour and preventing the grater from clogging.
2
✓
Sauté the rosemary in the butter over a medium heat for half a minute. Just until it starts to smell fragrant.
Tip: Heat is needed to release the essential oils, but butter browns quickly and the herb can burn, so stay alert!
3
✓
Pour in the orange juice and add the honey. Bring to a boil.
Tip: Honey not only sweetens but also gives body and shine to the sauce.
4
✓
Mix the cornflour until smooth in the cold water, then drizzle into the boiling liquid whilst stirring constantly.
Tip: Cornflour only thickens at boiling point (gelatinisation), but must be dissolved in cold liquid first to prevent clumping in the hot medium.
5
✓
Add the salt, pepper, and orange zest. Cook for another 2 minutes until thickened.
Tip: Add the orange zest only at the end to preserve its fresh, 'perfumed' aroma, which would evaporate during cooking.
6
✓
Strain if you want a completely smooth sauce, or leave the pieces in for a rustic effect. Serve warm.
Tip: Straining creates a more elegant, restaurant-style effect.
