For the base
For the topping
- STEP 1
Put the cashews in a large bowl, pour over boiling water and leave to soak for 1 hr. Meanwhile, blitz the ingredients for the base with a pinch of salt in a food processor. Grease a 23cm tart tin with coconut oil, then press the mix into the base and pop in the fridge to set (about 30 mins).
- STEP 2
Drain the cashews and tip into the cleaned out food processor. Add all the remaining topping ingredients, reserving a quarter of the lemon zest in damp kitchen paper to serve, then blitz until smooth. Spoon onto the base and put in the fridge to set completely (about 2 hrs). Just before serving, scatter over the reserved lemon zest.
