Before we embark on this sweet journey, it's crucial to understand how high altitude affects candy-making. Lower atmospheric pressure reduces the boiling point of sugar, which means we need to adjust our cooking time and temperature to prevent burning. Additionally, humidity levels affect the rate at which water evaporates, making it essential to account for these changes. Now that we're well-equipped with knowledge, let's get started on this delectable adventure!

Preparing Your Environment and Tools

To create the perfect caramel, you'll need an accurate candy thermometer that reads in increments no larger than 10°F (6°C). A 3- to 4-quart (2.8-3.8L) stainless-steel saucepan with thick, sturdy sides will provide ample room for the caramel to expand as it cooks. Additionally, have a 1-quart (946ml) glass measure filled with water ready at your side – this will help us check the caramel's readiness.

Lastly, lightly grease an 8-inch (20cm) square baking pan with cooking spray or butter. This will ensure easy removal of the caramel later on. Now, let's dive into the actual cooking process!

Caramelizing at High Altitude

The key to creating soft, velvety caramels at high altitudes is to cook the sugar mixture at a slightly lower temperature and for a shorter duration than at sea level. By adjusting these factors, we prevent the sugar from burning and ensure a perfectly creamy result.

Combining Ingredients and Cooking

In your prepared saucepan, combine the granulated sugar, light corn syrup, and ½ cup (120ml) of the heavy cream. Stir gently to combine, being careful not to splash the mixture onto the sides of the pan. Cook over medium heat, allowing the mixture to cook undisturbed until it comes to a boil.

Once the mixture begins to boil, insert your candy thermometer, ensuring it's immersed but not touching the bottom of the pan. Clip the thermometer into place, and continue to cook the mixture, without stirring, until it reaches 280°F (138°C). This should take approximately 10-15 minutes at high altitudes.

Monitoring and Finishing the Caramel

As the mixture approaches 280°F (138°C), keep a close eye on it, as the temperature can quickly rise at high altitudes. Once it reaches 280°F (138°C), use a pastry brush dipped in water to gently wash down the sides of the pan, removing any sugar crystals that may have formed.

Carefully and slowly add the remaining 1 cup (240ml) of heavy cream to the sugar mixture. Be cautious, as the cream may spit and bubble. Continue to cook the mixture, stirring gently, until it reaches 230°F (110°C). At this point, remove the pan from the heat source.

Gently stir in the pieces of butter, fleur de sel or sea salt, and vanilla extract until the butter has fully melted and the mixture is smooth and well combined. Pour the caramel into the prepared baking pan, spreading it out evenly with a spatula or the back of a spoon. Allow the caramel to cool completely at room temperature, uncovered, for about 2-3 hours or until firm.

Finishing and Serving Your High-Altitude Soft Caramels

Once your caramels have cooled and firmed, carefully cut them into 1-inch (2.5cm) squares using a sharp knife, lightly-oiled for easy slicing. Wrap each piece in wax paper or parchment, twisting the ends to secure, and store them in an airtight container at room temperature. These mouthwatering morsels will keep for up to two weeks, though we suspect they won't last nearly that long!

Enjoy your homemade, high-altitude soft caramels as a delightful snack, a sweet treat to share with friends, or even as a thoughtful gift for neighbors and loved ones. Happy cooking, and here's to elevated adventures in candy-making!
