We're going to build a hash that stores the recipe of Karlie Kloss' Perfect 10 Cookie. Think of the Perfect 10 cookie as an oatmeal cookie meeting an energy bar! It's made with gluten-free oats, almonds, mini chocolate chips and sweetened with agave. Each purchase of a Perfect 10 provides ten school lunches to hungry children around the world.

And as a reminder, a hash is a data structure, similar to an array, but instead of using numbered indexes to access data we linke each piece of data with a string (or symbol). Hashes looks like this:

student_ages = {
  :victoria => 25,
  :arel => 27,
  :carley => 25,
  :jordan => 28, 
  :al => 26
}

In this example, the hash is stored in the variable student_ages. Each age is stored in a key value pair: the name is the key and the value associated with it is the age. If you wanted to access the age of Arel, you would access it by calling student_ages[:arel]. Hashes are great because they allow us to store data with additional context. If we just stored everyone's ages in an array student_ages = [25, 27, 25, 26], we would have know idea which age belongs to whom!

More information about hashes can be found in the docs.

This is a test driven lab so open the lab in the Learn IDE. Then open recipe_hash.rb and follow the instructions in the file! Don't forget to run learn (from the main directory for this lab) as you work to make sure you are passing the tests.

You're going to write your code in recipe_hash.rb. Open recipe_hash.rb and follow the instructions in the file!

Here's a version of this Perfect 10 Cookie recipe so you can make some on your own! (Recipe makes 12 cookies).

2 cups almond flour
1 cup gluten freewhole oats
½ tsp. kosher salt
½ tsp. baking powder
¼ tsp. baking soda
½ tsp. Xanthan Gum
¼ cup slivered almonds, lightly toasted
¾ cup mini dark chocolate chips
½ cup olive oil
¼ cup agave

Heat the oven to 325º.

Mix the dry ingredients together in a bowl (you can use a mixer if you prefer). Add the liquid ingredients and paddle until well combined.

Scoop cookies firmly with a 2¼-inch ice cream scoop onto a parchment-lined sheet pan. Flatten each mound of cookie dough fully with the palm of your hand into a 3-inch round.

Bake cookies for 10-12 minutes or until golden brown. Cool completely on the pan. Store in an airtight container in the fridge, or eat right away.
