What other citrus fruits can I use in this recipe?
Yes, absolutely! You can use lime or grapefruit zest and juice to create different variations of this citrus slice.
How do I crush the biscuits without a food processor?
You can place the biscuits in a zip-lock bag and crush them with a rolling pin or a heavy object until they are fine crumbs.
Why is my citrus icing too runny or too thick?
If your citrus icing is too runny, add more sifted icing sugar, a tablespoon at a time, until you reach the desired consistency. If it’s too thick, add a little more lemon or orange juice to thin it out.
Expert Tips
- Measure your baking ingredients accurately: Check out my helpful guide on how to measure basic ingredients.
- Consistency of the Base: Make sure the biscuit crumbs are finely processed for a smooth base. This helps in forming a solid layer that holds together well when sliced.
- Even Spreading: Use the back of a spoon, a small offset spatula or your hands to press the base mixture firmly into the pan. This ensures the base is compact and even, which is crucial for a neat slice.
- Sifting the Icing Sugar: Always sift your icing sugar before mixing to avoid lumps in your icing. This creates a smoother finish.
How to store citrus slice
Storage: Store the slice in an airtight container in the refrigerator for up to 1 week.
Freeze: For longer storage, wrap the entire slab or individual slices in cling film, then place in a freezer-safe bag or container. It can be frozen for up to 3 months.
Thaw: Thaw the slices in the refrigerator overnight. For quicker thawing, leave them at room temperature for a few hours until they are soft enough to eat.
