Pre heat oven to 200° fan forced. (Place pizza stones into oven if you have them).
While dough is rising, make the crumble topping and stewed pears.
To make the Crumble - combine the spelt flour, plain flour, butter, oats and brown sugar together of 5 seconds on speed 4. Set aside in a small bowl.
Stewed pears. Without cleaning the bowl, add pears, sugar, citric acid, vanilla and agar agar. Cook for 10 mins 90° reverse speed stir. Place the basket on top to help pears reduce. It will thicken more as it starts to cool slightly.
Divide pizza dough into 2 - 4 portions depending upon how many and how big you would like your pizzas. Roll out portions of pizza base into rounds 5mm thick approx. (I roll my bases on baking paper to make it easier to transport between bench to trays to oven).
Slightly curl the edges up all around the edge of the pizza so the mixture won't run off during cooking.
Spoon some of the stewed pears over the base of the pizza.
Sprinkle a generous amount of the crumble over the top and right to the edges.
Place pizza in oven on the stones and cook for 15 - 20 mins or until base is cooked, lightly golden and the crumble has browned slightly. Cut into wedges with a pizza cutter or knife.
Enjoy warm served with cream or ice cream.
Notes
If you happen to have any left over stewed pears and crumble, place into little ramekin dishes and bake for 15 - 20 mins.
