Frequently Asked Questions

How do you adjust candy temperature for high altitude?▼

To adjust any candy recipe for high altitude, first determine the local boiling point of water (which drops about 1°F for every 500 feet or 2°F per 1,000 feet of elevation). Calculate the difference between sea-level boiling point (212°F / 100°C) and your local boiling point. Then subtract that exact number of degrees from the recipe's recommended cooking temperature. For example, in Denver (5,280 ft), water boils at 201.4°F (10.6°F below 212°F). If your fudge recipe calls for 238°F, cook it to 227.4°F (238°F - 10.6°F).

Why does candy need a lower temperature at high elevations?▼

Candy making is not about heating sugar to a specific thermal state, but rather boiling off water until an exact percentage of sugar concentration (Brix) is reached. Pure water boils at 212°F at sea level, but under lower atmospheric pressure at altitude, water molecules escape into vapor at lower temperatures. Because dissolved sucrose elevates the boiling point of the solution relative to pure water, the syrup reaches the critical sugar concentration (e.g., 85% for soft ball fudge) at a correspondingly lower boiling point. If you cook candy to sea-level temperatures at high altitude, you will boil away too much water, turning tender fudge into hard, crumbly brick.

What is the boiling water test for candy thermometers?▼

The boiling water test is the most accurate way to calibrate your candy thermometer before making a batch. Bring a pot of plain water to a rolling boil, immerse the bulb or probe of your candy thermometer (making sure it doesn't touch the bottom or sides of the metal pot), and read the temperature after 2 minutes. Note the reading: if it reads 202°F, your boiling point is 10°F below sea level (212°F - 202°F = 10°F). Subtract 10°F from whatever temperature your recipe states. This method automatically accounts for your exact altitude, today's weather barometric pressure, and any factory calibration error in your thermometer.

How much extra water should I add to candy recipes at high altitude?▼

At elevations above 2,500 feet, water evaporates much faster than at sea level due to lower atmospheric pressure. Because the liquid boils off so rapidly, the temperature rises before the granular sugar crystals have sufficient time to dissolve completely, which causes grainy, crystallized candy. Confectioners recommend adding 1 to 2 tablespoons (0.5 to 1.0 fl oz or 15 to 30 ml) of extra water for every cup of sugar in the recipe. The extra water will boil off cleanly, but guarantees 100% sucrose dissolution before the syrup reaches critical temperature.

How do corn syrup and cream of tartar prevent candy crystallization?▼

Corn syrup consists of glucose and higher saccharides, which physically block sucrose molecules from aligning into rigid crystal lattices. Cream of tartar (potassium bitartrate) is a mild acid that causes acid hydrolysis (inversion), breaking some sucrose into fructose and glucose (invert sugar). At high altitudes where rapid evaporation accelerates crystallization risks, adding 1 tablespoon of light corn syrup or 1/8 teaspoon of cream of tartar per 2 cups of sugar creates a chemical shield that keeps caramels silky and lollipops glassy.

How does stormy weather or low barometric pressure affect candy making?▼

A passing low-pressure weather system or rainstorm can lower local atmospheric pressure by 0.5 to 1.0 inHg (17 to 34 hPa), which further depresses water's boiling point by 1°F to 2°F on top of your elevation offset. High humidity also slows the cooling and setting of hygroscopic confections like hard crack lollipops and toffee, causing them to absorb ambient moisture from the air and turn sticky. For best results, use the live boiling water calibration on stormy days and avoid making hard candies when relative humidity exceeds 60%.
