Treat ingredient names that mean the same thing as one

"Mozzarella cheese" in one recipe and "mozzarella" in another should count as one thing on the grocery list and in filters, while "bread" and "bread flour" stay apart. The idea: built-in synonyms for each language, your own aliases on top, and a question before anything is merged. How much automatic matching would you trust, and how much would you rather correct by hand? Tell us in the comments. Suggested by a beta tester.
