How to loop through many to many?

I have a query that returns data like this: 




   +-----------+---------------+---------------+--------------+
    | recipe_id | name          | ingredient_id | item         |
    +-----------+---------------+---------------+--------------+
    |         1 | Apple Crumble |             1 | apple        |
    |         1 | Apple Crumble |             5 | flour        |
    |         1 | Apple Crumble |             7 | butter       |
    |         1 | Apple Crumble |             8 | sugar        |
    |         2 | Fruit Salad   |             6 | fruit juice  |
    |         2 | Fruit Salad   |             2 | banana       |
    |         2 | Fruit Salad   |             1 | apple        |
    |         2 | Fruit Salad   |             3 | kiwi fruit   |
    |         2 | Fruit Salad   |             4 | strawberries |
    +-----------+---------------+---------------+--------------+

How do i loop through and remove the duplicate records but keep the items for each? so something like this:

1 Apple crumble 1 apple, 5 flour, ... .. ..
