Hi there,

How about something like:

if(grocery_item.has_value?("Bread"))
  grocery_item["food"] = true
end

There's probably other ways of adding to a hash, but that's the one that came to me first!

I had it like this and was stuck on it for a while:

if grocery_item.has_value?("Bread")
  grocery_item = { "food" => true }
end

The Bummer message doesn't help at all when it says the has_value? method is not being called. It says to add "food" as a key and true as the value. My code follows exactly what the videos are teaching. The challenge instruction should to be reworded so it doesn't mislead or confuse:

... create a new key in the hash called "food" and set it to true.

Doesn't your line:

grocery_item = { "food" => true }

completely overwrite the grocery_item hash? It is declared in the same way:

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }

so I'm not sure you're adding to the hash, as required?
