Can I Use Raspberries Instead Of Passionfruit For The Passionfruit Curd?

Our answer

Nigella's recipe for Passionfruit Curd (from HOW TO BE A DOMESTIC GODDESS) uses passionfruit juice to make a curd, along with butter, eggs and sugar. Curds are thickened mainly by cooking the eggs in the mixture, though the acid in the fruit juice also helps slightly in the thickening process.

In HOW TO BE A DOMESTIC GODDESS, Nigella has a recipe for Cranberry Curd. So it is possible to use other sharp fruits to make curds and we suspect that it is possible to use raspberries as well. For the Passionfruit Curd you need 150ml (just under 2/3 cup) of passionfruit juice. We would suggest pureeing raspberries, sieving them to remove the seeds then adding enough lemon juice to make a fairly sharp raspberry puree. The amount of lemon juice you need to add will vary depending on the raspberries but it needs to be sharp-sweet. Use 150ml of this puree instead of the passionfruit juice in the recipe (any leftover juice can be sweetened and used as a sauce). However, please note that as we have not tried the recipe ourselves with raspberries, we are unable to guarantee the results.
