- 1 ½ cups raspberries fresh or frozen
- ¼ cup sliced almonds plus extra for topping
- Zest of 1 lemon
- Optional: 1 tbsp lemon juice for brightness
Custard
- 6 large eggs

Notes
This recipe freezes well.
Substitute any type of berries for the fruit, or even canned peaches or apple pie filling.
Skip the lemon syrup if you like. You can use nut milk instead of dairy milk as well. Almond milk or coconut milk work best.
