The process behind pralines is not a difficult one. Sugar, butter, and cream are put into a pot to boil, and the pecans come in during the boiling. The mixture is stirred occasionally until it has reached 240 degrees, which a chef normally tests with a candy thermometer. When it has reached this temperature, the pot is removed from heat and allowed to cool for a few minutes. Afterwards, vanilla extract is added in and the mixture is stirred until it thickens. The last step is to spoon the mixture onto a baking sheet. They should begin to set and look like cookies.
This process is rather common. The biggest thing to watch out for, though, would be the quality of the ingredients. This is especially true for the pecans. If you are shopping at a supermarket, many of the products that you see are likely mass produced with the cheapest ingredients possible in order to save money. This affects the taste and will likely be very noticeable to you. Local sellers, both in your area and online, usually choose the higher quality ingredients. This will result in an improved flavor and texture that will change how you feel about the candy.
Mass produced products might also have a different process. Many try to shorten it in order to get the pralines shipped quickly by producing them in a factory. This change in the process can also affect the texture. If you were to compare mass produced to handmade products, you could spot this difference rather quickly. Since local sellers rarely have an entire factory to use, they are going to be doing it all by hand. From adding the ingredients to placing the mixture onto the sheet, it is all done carefully by the chef. In the South, finding these types of sellers is easy because of the candy's popularity.
Make sure that you do your research on the seller in general. A good seller is about more than the process and the ingredients. There has to be trust and great service there, too. Having everything in one will ensure that you receive and enjoy your pralines. Many sellers do have great respect for their job and products, so it should not be too difficult to find something good. Contact sellers in your area or online and begin learning more about their process, ingredients, and business.
