You can use backticks (`) around table & column names (so that illegal character names in such names are accepted), but not quotes. Read about table & column names in the manual page on SELECT expressions.

To improve query readability and maintainability, use aliases for table names. Read about aliases in the manual.

You want the row count, or the vote count for a user? If its to be the vote count ...

SELECT SUM(r.vote)
FROM recommendations r
JOIN products p ON r.product=p.id
WHERE p.author=':username' ;
