For the crumble:
For the strawberries:
Heat the oven to 360°F.
Mix all the ingredients for the crumble together using your hands, then put a piece of parchment paper or silicone sheet. Bake for 10 minutes or until brown. Allow to cool, chop and set aside.
Macerate the strawberries chopped in halves along with the rest of the ingredients and allow to set for 30 minutes.
Serve in small bowls, adding the berry ice cream first, then macerated strawberries and then finish with pistachio crumble.
