Tips for passionfruit icing

If you don’t have fresh passionfruit, you can use the same amount of canned passionfruit which is available at most supermarkets. Canned passionfruit is usually a bit sweeter than fresh passionfruit, so test for sweetness. If you prefer your icing more tart, you can add a small squeeze of lemon to the passionfruit before making the icing.
If you want to make smooth icing without the seeds, simply strain the passionfruit pulp through a strainer and discard the seeds.
The icing will be runny at first, ice your vanilla slice or baked goods and allow it to set for about 30 minutes before slicing.

Other ways to use passionfruit icing

  • Spread over cakes or cupcakes
  • Fill melting moments
  • Use to glaze donuts
  • Drizzle on top of shortbread
  • Stir any extra through ice cream or yoghurt
