I'm wondering, can we come up with replacements for all these no doubt needlessly exotic ingredients? I'd start by swapping that salt for some good quality British sea salt!

Obviously the choc part would be dropped too for 100% localness ... I dunno, maybe strawberry or apple flavour or something would be just as nice anyway.
For the base:
300g Pecans or Almonds
1 tsp, Pink Himalayan Salt
200g, medjool dates
For the filling:
Blend the flesh of 4 medium, ripe avocados
150g Virgin coconut oil
Beans of 2 whole vanilla pods
200g raw cacao powder
Pinch of salt
300g coconut blossom sugar or agave nectar to taste.
Destructions:
In a food processor, blend the pecans or almonds (Preferably, soak them for around 6 hours and then dehydrate them. The soaking releases the enzyme inhibitors and makes them easier to digest)
Then add the Pink Himalayan salt or another good quality salt. To this, add the Fresh medjool dates. Blend until you have a ‘dough’, or until the mix forms a ball.
Press this mixture into the bottom of a mould. Cover in cling film and leave to harden in the freezer till you are ready to pour on the filling. I like to use a silicone mould. They are freezer safe and easy to get the tart out once it has set.
Blend your filling ingredients until smooth, and then pour onto the base.
