Does molasses last forever?

  • 5

I was looking at a recipe I'm going to cook soon and I noticed it needs a little molasses. Surprisingly enough I found a bottle in the pantry, but have no idea how long it's been there. It still moves around in the bottle well (hasn't solidified) but I have no idea if still usable. My guess is yes, but does anyone have any information? Thanks very much in advance.

  1. I have the same question about 'cornstarch'...How long does it keep and is the effectiveness compromised? Corn Syrup as well?

    1. My guess is that molasses, corn syrup and cornstarch would all last for years. Molasses and corn syrup are sugar, which is a natural preservative. And I can't imagine that cornstarch would go bad.

        Thanks so much ... my own instincts were telling me it would be fine, but it is good to hear the reasoning. And yes, I've had corn starch last for ages.

      2. A google result:

        "Liquid sweeteners do not have quite the longevity of dry sugars. Honey, cane syrup, molasses, corn syrup and maple syrup may crystallize or mold during long storage. These syrups are chemically not as simple as table sugar and therefore lose flavor and otherwise break down over a long period of time"

        1. I don't know about it lasting forever, but I just used some molasses from a half-empty jar that must have been around for 10 tears. I was making Swedish Limpa Rye Bread and the recipe called for 2 Tbsp. It came out fine so I wouldn't hesitate to use the same molasses again as long as it's appearance and smell remain stable.
