I've never attempted to make homemade lemonade before and my youngest has been urging us to have a go for a while, so we took a bag of lemons and turned them into this:
It's another Nigella Lawson recipe from Nigella Express (Cloudy Lemonade for a Sunny Day). The recipe's not on her website but it's very simple and involves blending up roughly chopped lemons with sugar and fizzy water. It was lovely and refreshing, although I might do it slightly differently next time (using the blender instead of food processor and blending with a sugar and water syrup first, then adding fizzy water later). Or I may not make any changes at all, as the whole litre that we made this time disappeared very quickly!
