I have some recipes from my grandma, that do not have how long they are good for....

Is there some way to figure this out?

Here is one

1 white potato (cooked and mashed)
7 cups of powdered sugar
1 tsp mint flavor

Mix, and dip in chocolate

I am no way a food scientist, but I wouldn't eat mashed potato after it had been in my fridge for around 3 days, for example. I know it is mixed with a lot of PS, which is a preservative, and covered in chocolate so it will be airtight, but even so...I would still say around 2-3 days?

HTH

Potatoes will start to ferment after a while, there's a type of sourdough that's made with mashed potatoes. (I think I'll make some today, thanks for the reminder, haha!) 2-3 days in the fridge sounds about right.

oh really?

I have made this recipe before, and it has lasted 2 weeks, before they were all gone......

hmmmm, well thanks for that


But I wasnt just talking about this recipe, Is there anyway as a baker/confectioner, to figure out the expiration dates of a recipe

Hahaha, what, they didn't turn to sourdough? Haha!

Here's a chart that mostly explains what the sell-by date means, but on the sidebar on the right side of the page it has a chart of different types of food and how long they should last. http://www.gourmetsleuth.com/Articles/Nutrition-Health-Food-Labeling-646/food-expiration-dates.aspx#r1

I don't think that's exactly what you're looking for, but it's the closest thing I could find, everything else just looks like it has individual ingredients listed.

No actually they were still good

Thanks tho

Actually in one of the links JanH posted, one person said that the potato candies last indefinitely (or as long as your hand stays out the jar anyway). Incredible really!

oh thats great to know thank hyou!
