dobbiamo saltare tutte le ricette che hanno ingredienti diversi da pollo e maionese, quindi qualcosa come di seguito dovrebbe funzionare:
SELECT * from recipe r
INNER JOIN relationship ri on r.id=ri.recipe_id
INNER JOIN ingredients i on i.id=ri.ingredients_id
WHERE i.ingredients_name IN ('chicken','mayonnaise')
and r.id not in (select r.id from recipe r
INNER JOIN relationship ri on r.id=ri.recipe_id
INNER JOIN ingredients i on i.id=ri.ingredients_id
WHERE i.ingredients_name not IN ('chicken','mayonnaise'))
