Peel and slice pears evenly and add to a baking dish. Next, pour the water over the top of the sliced pears.
Mix the cinnamon with 1/4 cup of the brown sugar. Sprinkle the cinnamon and brown sugar mixture over the pears.
In a separate bowl, add the remaining brown sugar, flour, salt, and oatmeal and combine.
Work in the butter to the oat mixture until crumbly. Be careful not to over work it and melt or soften the butter too much.
Spread the crumble mixture over the pears and gently spread it evenly.
Bake for 30-35 mintues or until pears are soft and crumble mixture is golden brown.
I used a 9X13" baking dish for this recipe. You can use a smaller one if needed, just be sure to adjust the baking time slightly.You'll want the pears to be soft and tender, not mushy. And the cruble to be golden brown, but not overly crunchy.
