I make a lemon juice and caster sugar dressing for sliced lettuce, mainly cos, as my German mother did as I was growing up and although I absolutely love this salad and the freshness of it I was wondering if you could recommend a different citrus to jazz it up a bit and for a bit of a change. All ideas will be greatly appreciated!
Most salad dressings have a combination of acid, in the form of citrus juice or vinegar, and fat, in the form of oil or a dairy product. A pinch of sugar can be added to temper the sharpness of the acid and other ingredients such as herbs, chillies, soy sauce or fish sauce can also be added. Lime juice can be a useful ingredient in a salad dressing and in Nigella's Spinach, Avocado And Pumpkin Seed Salad lime juice is combined with avocado oil. The zest of the lime is added too to increase the citrus flavour. Lime is used again with sesame oil in the Chicken, Mango And Chilli Salad.
Nigella also likes to use the juice of Seville oranges when they are in season. The Seville orange juice is more tart than regular orange juice. However they have a short season and can be difficult to source, so a combination of orange and lime juice makes a good substitute. Try Nigella's Gingery Hot Duck Salad, which uses a combination of lime and orange juices along with fresh ginger and sesame oil.
