Again, I'm not actually suggesting that you merge this in and remove all your code. This just makes it easier to leave feedback :smile: 

Please submit a help request for any questions that you have about my comments.

### Don't merge this pull request
This could be extracted out to a method as well as simplified a little bit:

```ruby
def all_recipes
  db_connection do |conn|
    conn.exec('SELECT id, name FROM recipes ORDER BY name')
  end
end

get '/recipes' do
  @recipes = all_recipes

  erb :index
end
```
