Zucchini Crisp

I was looking through my recipes on here and couldn't believe I hadn't added this one. It's Earl's favorite and I've been making it for him for more than 8 years. Honestly, if you don't tell anyone it's zucchini they'll swear it's apples. An especially good recipe if you over did zucchini in the garden!

Crisp Mixture:

4 cups all-purpose flour
2 cups light brown sugar

1/2 teaspoon salt

3/4 pound butter or margarine (3 sticks)

Filling:

8 cups prepared zucchini (About 3-4 medium,which have been peeled, halved lengthwise, seeded and thinly sliced. I sometimes just grate them.)

1/2 cup lemon juice

2 tablespoons apple cider vinegar

1/2 cup Crisp Mixture (see above)

1 to 1 1/2 cups light brown sugar

1/4 teaspoon nutmeg1 tablespoon cinnamon

To prepare the Crisp Mixture:

In a large bowl, stir together the flour, brown sugar and salt . Using a pastry
blender, cut in butter or margarine until mixture is crumbly; set aside.

To prepare the Filling:

In a large saucepan, over medium-high heat, cook the zucchini, lemon juice and vinegar together, stirring occasionally, until the zucchini is very tender, but still retains its shape. Stir in 1/2 cup of the prepared Crisp Mixture, and the brown sugar, nutmeg and salt. Simmer over low heat several minutes, stirring constantly, to allow the filling to thicken, and the flavors to blend.

Pat half of the remaining crisp mixture into a 9 x 13-inch pan. Spread the zucchini filling over the base. Sprinkle the rest of the crisp mixture evenly over the filling; press lightly. Bake at 375 degrees F for 30 minutes, or until bubbly hot throughout, and top is lightly browned.

Serve warm or cold. Very good with vanilla ice cream.
