It depends on what type of praline you order: Our Original Pralines are made from the original family recipe developed over 80 years ago. They contain no preservatives and are best consumed within a week of purchase. They never go “bad,” but after a week or so the sugar starts to crystalize and they lose the characteristic snap that you enjoy when biting them. Our Creamy Pralines are more fudge-like and they will last for up to eight months from production. The expiration date is clearly printed on each wrapper. Our Chewy Pralines last about six weeks, depending upon the environment (humidity, temperature). If your Chewy Praline feels harder than you prefer, just pop it in the microwave for ten seconds and all the delicious softness will come right back.
