How to Caramelize Vegetables to Enhance Their Flavor, Color and Appeal

The word "caramel" may mistakenly be taken to mean sweet, sugary or high in calories. The process of caramelization refers to the browning of sugar that occurs naturally in the food. Or tiny amounts of sugar are added in the form of glucose, fruit juice concentrate, sucrose, honey or molasses.

Caramelizing creates a sweet nutty flavor to the food, and generally turns the food to a brown color (they turn 'caramel'). The food is effectively covered in a caramelized sauce or dressing. It requires high temperature from a grill, pan or oven to caramelize the sugar.

Most vegetables and fruit, which have their own sugars, will caramelize well when exposed to high temperatures. Sweet fruit like pineapples, figs, peaches, and bananas will caramelize very well. Most vegetables have enough sugar to caramelize, though you can hasten and enhance the process by adding small amounts of sugar, syrup or honey. The trick to finding the best vegetables for caramelizing, is to find varieties have the most natural sugar. Obviously, many of the best ones are bulbs or root vegetables. Some good choices are carrots, beets, parsnips, onions, peppers, pumpkin squash and corn.

Another trick is to cut the vegetables so that a large surface area is exposed to the flame, grill, pan or heat in the broiler of oven. This will hasten the process. Using a flame is a quick way to caramelize vegetables, but you can use searing in a pan, grilling on a hot plate, broiling or roasting in the oven. Remember to spread the vegetables in a shallow layer in the pan or oven sheet, with the large surfaces orientated to get the most heat.

If no sugar is added and the vegetables are dry the process is referred to as Dry Caramelization. For Wet Caramelization, a small amount of sugar is dissolve in a tiny amount of water to form a syrup. The vegetables are tossed in the syrup to hasten the caramelization process. Wet caramelization can also be done in the microwave. The color produced by of the wet caramelization process will generally be lighter than the dry process.
