MySQL - Getting top 10 records

Hi, Ok I’m having a moment and I cant seem to get my head around this.

What I need to do is get the 10 most reviewed products from a db, whilst joing onto the product table to get its name, so effectively 2 tables:

reviews

rev_id
rev_text
rev_parent (contains id of the reviewed product)

products

product_id
product_title

how could I achieve this?
