Yes. At current version, to prototype the recommender, we did not exclude 
recipes not containing the food, but deprioritized them in the search result. 
At its current version, the recommender ranks the recipes according to SCORE 
which is a function of

SCORE ~ f(#matches between provided foods and recipe foods, #matches between 
blacklist and recipe foods, recipe rating)

where f is a linear function.
