FAQs
Fudge is one of the rare exceptions to the rule that sugar crystals are not desirable in candy. Tiny microcrystals in fudge are what give it its firm texture. The crystals are small enough, however, that they don't feel grainy on your tongue, but smooth.
How does fudge relate to chemistry? ›
When making fudge, heat and acid work together to convert sucrose – basic white sugar – into its two components, glucose and fructose. When these sugars are present, they prevent sucrose from turning into big sugar crystals.
What is the science behind candy? ›
In general, candy is made by dissolving sugar into water to create a solution. Granulated sugar, the most common type used in candy-making, is sucrose, a disaccharide molecule made up of glucose and fructose. When you force these two molecules to break apart, a very tasty reaction occurs: caramelization.
Why must fudge be vigorously beaten after it has cooled to a specific temperature? ›
This is done after about 15 minutes of cooling when the mixture reaches 110 to 113 degrees Fahrenheit. The goal of beating the mixture is similar to the no-stir phase: it prevents a lumpy fudge. As the fudge cools down, it solidifies and beating introduces air inside which keeps it from clumping together.
What makes fudge special? ›
Fudge is one of the rare exceptions to the rule that sugar crystals are not desirable in candy. Tiny microcrystals in fudge are what give it its firm texture. The crystals are small enough, however, that they don't feel grainy on your tongue, but smooth.
What is the principle of fudge? ›
Heating the sugar and milk mixture allows the milk to dissolve more and more sugar, and by the time the mixture is boiling, all the sugar is dissolved. The general principle is that at a particular temperature, a given solvent (in this case, milk) can dissolve only so much of a particular solute (sugar).
How to make fudge more solid? ›
How do you fix fudge that is too soft? Bring the fudge back to a boil with 1–2 US tbsp (15–30 ml) of cream. If your fudge is soft or runny, it probably didn't come up to a high enough temperature while it was cooking. Put it back into the saucepan and add 1–2 US tbsp (15–30 ml) of 35% fat whipping cream.
What would cause fudge not to harden? ›
The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft. That's why we recommend investing in a sugar thermometer. Another reason your Fudge is not setting is that the ratio of liquid to sugar is too high.
Why is my 3 ingredient fudge not setting? ›
Why won't my 3 ingredient fudge set? This often happens when the condensed milk and chocolate chip mixture isn't hot enough to start. Everything must be completely melted before it is transferred to the pan to cool.
Why can't you make fudge when it's raining? ›
As strange as it sounds, it is a fact that weather affects fudge making. This is because when the weather is damper with an increased humidity level your Homemade Fudge Recipe will take longer to boil.
Options for what you can do with your unset fudge:
OPTION 1) Depending on how runny it is, you can either use it as a frosting for cakes, or a sauce for ice-cream. OPTION 2) Freeze it overnight. Cut it into squares. Cover each square thickly in melted chocolate, ensuring no part of the fudge is exposed.
What is the secret to non-grainy fudge? ›
Brush the sides of the pan with a wet brush at the beginning of cooking to dissolve sugar crystals stuck to the sides. Never stir the mixture during cooking or sugar could crystallize again. The mixture may seize and become grainy. Use a candy thermometer or conduct a cold water test to check if the fudge is done.
How is chocolate related to chemistry? ›
The main flavor compounds in chocolate are polyphenols, present in raw cocoa bean and going through various forms during production, and pyrazines formed during production, followed by aldehydes, ketones, and esters.
How is food related to chemistry? ›
Chemical substances can play an important role in food production and preservation. Food additives can, for example, prolong the shelf life of foods; others, such as colours, can make food more attractive. Flavourings are used to make food tastier.
What's chocolate and how does its chemistry inspire such cravings? ›
Chocolate is the richest natural source of theobromine, but coffee and tea contain some of it too. Theobromine chemically resembles caffeine and has a similar stimulating effect on our brains. The combination of theobromine and caffeine found in chocolate is believed to create the small lift we feel after eating it.
What is the chemistry of sugar? ›
The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from these three elements, sugar is a carbohydrate.
