To make a quick crisp for two, simply fill a baking dish with two to four cups of prepared fruit, sweeten if necessary, and top with a crumbly crust. Bake about half an hour (45 minutes for apples and pears) at 350. 

Some lovely fruit combinations: 

Peaches and blackberries or raspberries

Blueberries and plums

Apples and cranberries

Rhubarb and strawberries

Crunchy toppings

1 c. regular oatmeal

½  c. brown sugar

½ c. flour

1 t. cinnamon 

¼ c. defrosted apple juice concentrate 

Mix the first four ingredients; drizzle apple juice into the oatmeal mixture. Stir until the mixture forms small clumps. Spread mixture on top of the fruit and bake 30 minutes at 350. 

Another topping

⅓ c. chopped toasted walnuts

½ c. flour

½ c. rolled oats

½ c. brown sugar

1 T. granulated sugar

¼ t. cinnamon

¼ t. nutmeg

¼ c. softened butter

Mix dry ingredients well and then cut in the butter until it forms small clumps. Continue as above.
