You can caramelize onions with either vegetable oil or olive oil.
However the use of olive oil when caramelizing onions adds a rich and savory flavor to the caramelized onions.
But vegetable oil such as grapeseed oil or canola oil is preferred as it has a higher smoke point and prevents it from burning at higher temperatures and some people also use butter or even a combination of butter and olive oil for added richness and flavor.
You can also add some water, baking soda or even a bit of vinegar to the onions to make them caramelize faster.
When you add water to the onions, it speeds up the process of caramelizing of the onions by creating a more concentrated sugar solution.
Adding a 1/4 teaspoon of baking soda per pound of onions creates a high pH environment and can accelerate the browning reaction necessary for caramelization.
Adding water caramelize onions faster by steaming the onions and release the onions natural sugars, which then evaporate and concentrate and leads to quicker browning of the onions.
Caramelizing onions can take between 30 to 60 minutes although sometimes 30 to 45 minutes is enough for caramelizing onions.
Color of the food you're caramelizing is a good indicator of when the caramelizing of the food is done.
Look for a rich golden brown color to the food, although it should not be so dark that the food becomes bitter.
You can speed up the caramelization process by adding some water or baking soda although it can affect the final flavor and texture.
It takes between 8 minutes to 23 minutes to caramelize sugar, which also depends on the method and desired color.
8 to 10 minutes is what it takes for a golden brown caramel when caramelizing sugar and up to 23 minutes for a richer brown color to occur when caramelizing sugar.
You should also monitor the color of the caramelized sugar and remove it from the heat after it reaches your desired color.
The temp that sugar caramelizes is around 320 F degrees.
Complete caramelization, in which the sugar changes in flavor and color occurs at 320 F to 360 F.
When sugar is put in a pan and heated it eventually melts and at around 320 F to 338 F the sugar starts to turn brown.
When caramelized sugar is heated for too long it will burn the sugar and turn dark brown or even black in color and also take on an acrid and bitter flavor.
The sugar molecule will also break down and the reaction can even produce fumes and it will also become sticky instead of light brown, sweet and complex tasting syrupy solid.
To caramelize food you start by caramelizing the food on high heat and then switch to low to medium-low heat which allows the sugars in the foods to break down gradually and brown without burning.
Low and slow cooking of the caramelized food is key to caramelizing foods including onions.
To caramelize food you cook the food using a slow cooking process which requires a certain amount of heat to start the reactions.
Start with high heat and begin cooking the food over high heat which starts the caramelization process.
Then once the food starts to release it's moisture and begin to brown, you reduce the heat to a low setting or a medium-low setting.
While cooking and caramelizing the food, stir the food regularly to prevent burning of the food and also ensure even caramelization.
Continue to cook the food until the food reaches your desired flavor and color.
Then once the food has caramelized, remove the food from the heat and allow it to cool down.
Slicing foods such as onions before caramelizing the food can help them to caramelize evenly and you can also add a pinch of salt or sugar to speed up the caramelization process.
Caramelization does not reduce sugar, but instead caramelization breaks down the sugar and transforms sugar molecules into other compounds which result in a change of color and taste but not a reduction in the overall sugar content.
The process of caramelization is a chemical process in which sugar molecules in food, break down and react when heated, which results in a golden brown color and also a distinctive and complex flavor.
The process of caramelization is also known as pyrolysis and occurs when the sugar is exposed to heat and causes the sugar to oxidize and form new compounds which result in a caramelized substance and a rich, sweet and nutty flavor.
The difference between Maillard and caramelization is Maillard reaction is the interaction between two amino acids and reducing sugars which result in a broader range of complex and savory flavors.
Caramelization is the browning of the sugars in the food when it's heated, which leads to a sweeter, nutty and slightly bitter flavor.
Both Maillard reaction and caramelization are non enzymatic browning reactions that occur when the food is heated but they involve different chemical processes and produce distinct flavors.
Maillard reactions also occur in dried fruit and when champagne ages in the bottle.
Caramelization is an entirely different process from Maillard browning, though the results of the two processes are sometimes similar to the naked eye (and taste buds).
The 4 types of fodo that can undergo the Maillard reaction include.
Bread which develops a darker and thicker outer crust.
Eggs which creates a brown lining and crackled edges.
Meat and Fish which sears on a fine, crunchy brown outer coating.
Beer "while not food", malts are roasted to various degrees and added into the brewing process.
The Maillard reaction is a chemical reaction between amino acids (the building blocks of proteins) and reducing sugars (like those in molasses or fruit juice) that happens when food is heated.
This reaction is responsible for the browning and flavor development we see in things like seared steaks, roasted bread, and caramelized onions.
