I love making the Prodigious Pavlova from "Nigella Christmas". However, passion fruit is hard to come by in my neck of the woods. What would make a suitable substitution if I can't get them? Thanks! Josh Viles Auburn, Washington USA
Passion Fruit can sometimes be bought in the US via Amazon Gourmet, or it is worth checking Asian and Latin American food stores as passionfruits are popular in these cuisines. Passionfruit puree, without the seeds, can sometimes be bought frozen (some large Italian food suppliers have it) or in containers in ambient form on-line (it is worth looking on sites that sell cocktail mixers as it is sometimes used in cocktail bars).
If you still can't find it then you could substitute a seasonal fruit of your choice. Cubed mango would go well with the raspberry sauce or you could use Christmassy pomegranate seeds instead.
