I learned how to make tempura from a book.
Literal
Tempura [possessive-の] making-method [object-を] book [with-で] read.
天ぷらの作りかた ('how to make tempura') uses the ~方 (かた) pattern for 'how to do X.' 本で読みました ('read in a book') uses で for the source/means. A simple, clean sentence — useful for learners because 作り方 is one of the most versatile and practical noun patterns.
