Lemon Cake with Passion fruit syrup

It's been a while since I baked and after a trip to Melbourne, I've found that passion fruit cakes or tarts are very popular there, esp when they are in season. The nearest recipe I found that uses passion fruit, is this. I found the recipe from an Australian magazine. I wanted to make the syrup from the fruit itself. But, as they are not in season here, I used a pre-packed passion fruit juice.

The texture is a bit like Japanese cheese cake. But, no cheese were used. :-)
