get the name of product with the maximum number of orders

Question

I have 2 tables orders and product as orders has only one field (order_id) and the products have a reference to the order_id,

how to get the name of product with the maximum number of orders

I tried this query

SELECT   MAX(mycount) 
FROM 
(Select products.product_name , count(orders.order_id) mycount
FROM Orders, products
WHERE products.order_id = Orders.order_id
GROUP BY orders.order_id) 

but it only gave me the max value, how to add the name field (products.product_name) to the result??
