I originally found this on davidlebovitz.com. It is one of my favorite recipes. You can substitute just about any fruit. Apples or quince work great.
What you will need
3/4 cup (90g) AP Flour
3/4 tsp (3g) baking powder
1 pinch salt
3/4 cup (170g) sugar
1 tsp (4g) vanilla
8 tbsp (225g) butter, melted
How to cook
Whisk together flour, baking powder and salt.
Beat eggs until foamy. Whisk in sugar and vanilla.
Melt the butter and whisk half of it into the egg mixture.
Stir the dry ingredients into the wet ingredients.
Whisk in the remaining butter.
Preheat oven to 350ºF (175ºC).
Peel and halve the pears.
Remove the seed core with a small spoon. Slice out the stem.
Slice pears in wedges.
Fold the pears into the batter. Spread in a buttered baking pan.
Bake for 50 minutes
It looks best if you neatly arrange the pear slices on top before baking.
