;; Example:
;; --------------------------------------------------------------------
(let [ex [{:recipe/recipe_id "a1995316-80ea-4a98-939d-7c6295e4bb46"
             :recipe/public true
             :recipe/prep_time 5
             :recipe/name "Avocado Salad"
             :recipe/img "https://res.cloudina … cipe/vegie-salad.jpg"
             :recipe/favorite_count 5
             :recipe/uid "jade@mailinator.com"}]]
    (associate-by-kkeyword-value :recipe/recipe_id ex))
