In a small bowl, mix cottage cheese and baking soda. Let stand at room temperature for one hour. This allows the curds to break down, and melt smooth. Don't add more baking soda, it will taste funny, and don't worry if it's not perfectly smooth after an hour.
In a large saucepan, melt Butter and Process Cheese. Stir occasionally until completely melted.
Add the broken down Cottage Cheese and Parmesan Cheese, then stir until smooth.
Add in the Caraway seeds (maybe a teaspoon or more) Stir.
If mixture is very thick, add some milk.
Pour into containers (for serving or storing) and cool
Serve with Rye Bread, Crackers, Pretzels or a spoon!
*note- The texture is like a cream cheese or Brie Cheese... my daughter loves to warm it up in the microwave a bit so it's more of a dip.
