Lets start with preparing the fruit layer, Poach the pear, dried blueberries along with the wine for about 3-4 minutes. It should just start to tenderize. Add sugar and zest and keep aside for cooling.
Lightly whisk together milk, eggs and vanilla.
Sift all the dry ingredients together. Add the butter and half the egg mixture, and mix until dry ingredients are moistened. On medium speed, beat for one minute. If mixing by hand, mix for about 2 minutes.
Add the remaining egg mixture in two batches, beating for 20 seconds between each addition.
Pour the mixture in a baking pan (I used a 6 inch round pan)
For the crumble topping mix all the ingredients together till they just come together.
Spread the fruit layer on top of the cake batter and the crumble layer on top of it.
Bake in a preheated oven at 180C for about 60 minutes or so. I covered the cake with a foil after about 25 minutes to prevent the top from burning.
