Pineapple Bake

1 can (20 oz) chunk pineapples
1/2 cup sugar
3 Tbsp flour
1/4 cup melted butter
1 cup shredded cheddar cheese
4 oz sour cream
1/2 sleeve crushed ritz crackers (if you like crunch...I will omit if I make again)

Drain pineapples, saving 3 Tbsp juice.  Combine sugar and flour; add juice.  Add melted butter.  Stir in cheese, pineapples and sour cream.  Place in medium sized loaf pan.  Top with crackers (if you are using).  Bake at 350 for 20-30 minutes or until brown.
