Tips & Variations
- For a gluten-free option, substitute the plain flour with a gluten-free flour blend that measures cup-for-cup.
- If fresh passionfruit pulp is unavailable, you can use frozen pulp or a good-quality passionfruit juice concentrate.
- Adding a teaspoon of finely grated lemon zest to the filling enhances the citrus aroma.
- For easier slicing, use a sharp knife warmed under hot water and wiped dry before cutting.
Storage
Store the passionfruit slice in an airtight container in the refrigerator for up to 4 days. The topping may soften slightly at room temperature, so keep it chilled until serving. Leftovers can be gently reheated briefly in a low oven if desired, but it tastes best served cold or at room temperature.
