Mary Berry’s orange sauce is a classic British variation of the French “Duck à l’Orange.” It’s made from fresh orange juice, zest, stock, wine or vinegar, and a small amount of sugar or honey for balance. The sauce is reduced to a silky, syrupy consistency that coats the duck beautifully. The bright citrus notes cut through the richness of the duck, creating a perfectly balanced flavor profile that’s both refreshing and indulgent.
200ml fresh orange juice (from about 2 large oranges)
Zest of 1 orange
1 tbsp white wine vinegar or cider vinegar
1 tbsp sugar or clear honey
150ml chicken or duck stock
1 tbsp cornflour mixed with 2 tbsp water (optional, for thickening)
1 tbsp butter (for richness and shine)
Salt and freshly ground black pepper, to taste
Juice the oranges and grate the zest from one of them. Set aside. Mix the cornflour with water if you plan to thicken the sauce.
In a saucepan, combine the orange juice, zest, vinegar, and sugar (or honey). Bring to a gentle boil over medium heat, stirring until the sugar dissolves.
Pour in the chicken or duck stock and simmer for 8–10 minutes until the liquid reduces by about one-third. This concentrates the flavors and gives the sauce a rich base.
If you prefer a thicker sauce, add the cornflour mixture while stirring constantly. Simmer for 1–2 minutes until slightly thickened.
Remove from heat and whisk in the butter. This adds gloss and smoothness to the sauce. Season with salt and pepper to taste.
Pour the sauce into a jug or spoon it directly over cooked duck breasts, legs, or roast duck. It also pairs beautifully with chicken or pork.
