I'm not sure how to solve this exercise. I assume that checking the hash variable for the calories key and if so add a new key called "food" and set it to true would look like my code below.
When I submit my answer, I get "The food variable was not found".
I'm not a newb to programming in general, but perhaps I've missed something here. We just covered the .store method and if statements were covered a while back. What else could I need to check if a key exists and if so create another with a Boolean value?
hash = { "name" => "Bread", "quantity" => 1, "calories" => 100 }
if hash.has_key?("calories")
hash.store("food", true)
end

The challenge is not asking you to create a new hash key called "food." The challenge simply asks you to create a new variable called food. So instead of using
hash.store("food", true)
type
def food = true
Hope this helps!
