That vs. Which: Usage Guide
That and which are both used to introduce a restrictive clause, i.e., a clause that can't be removed without changing the sentence's meaning substantially or making the sentence incomplete or difficult to understand. In "The cake that/which they served was pink," the restrictive clause is "that/which they served." To remove it renders the sentence incomplete: what cake was pink? Which is used to introduce a nonrestrictive clause, i.e., a clause that adds information to the sentence but isn't essential for understanding the sentence's basic idea. In "The cake, which was delicious, was pink" the clause "which was delicious" adds nonessential information; we still know that the cake being discussed was pink. That formerly did this job as well, especially in poetry, but the use is now rare.
