Preheat oven to 350 degrees. Line a baking sheet with a silicon baking mat or parchment paper, add the almonds to the baking sheet. Roast for 12 minutes.

In a large pan, add in the granulated sugar, cinnamon and water; whisk everything together. Allow the mixture to come to a boil; add the almonds to the mixture. Cook and stir on medium-heat until the liquid evaporates and leaves a syrup-like coating on the almonds. Pour the almonds back onto the baking sheet lined with parchment paper or a silicon baking mat; separate the almonds and allow them to cool.
