Grandma Moore's Pineapple-Cheese Casserole

I have absolutely NO intention of ever making this recipe, but I thought I'd post it in case it brings back any fond memories for any of the sisters reading this.  Oh, and its always kinda fun to read a recipe from a different era :)

Grandma Moore's Pineapple-Cheese Casserole

1 20 oz can chunky pineapple, drained and liquid reserved
3 tablespoons flour
3 tablespoons sugar
1 1/4 cups shredded cheddar
1 1/2 cups crushed Ritz crackers
3 tablespoons melted butter

Arrange pineapple on bottom of greased 1 1/2 quart casserole. Stir flour and sugar together, and sprinkle over pineapple. Drizzle 3 tablespoons of pineapple juice over and top with cheddar cheese mixed with crushed crackers.  Drizzle butter over top.  Bake covered at 350 degrees for 15 minutes. Uncover and bake for 10 minutes more.
