NSPredicate filtering using set operations

I'm trying to filter such that criteria is met for each AND every item in a set vice each OR every item.

If I use groceryItem IN %@, desiredGroceries, it acts like an OR statement.

Example: I'm trying to view all grocery lists that included milk AND eggs (defined in desiredGroceries Set). If I use the above code, it returns all lists that included milk as well as lists that included eggs.
But I only want the lists that include both milk and eggs.

What's the correct Predicate for this?
