You're off to a good start!

The first problem is that method names are case-sensitive. There is no method named Has_key?, there is only a method named has_key?.

Once you have that fixed, hash.has_key? will return either true or false (true in this case). You need to use that value in an if statement.

hash = { "name" => "Bread", "quantity" => 1, "calories" => 100 }
if hash.has_key?("calories")
  # YOUR CODE HERE
end

Within that if statement, that's where you'll need to set the food variable.
