I recently got an email asking about how long certain foods last once they're opened or once you bring them home from the grocery store. This has always been sort of a mystery to me as well, we buy a lot of fresh vegetables so they usually get eaten or cooked quickly.
There are things like maple syrup, rice and pasta that you can keep for ages if you've stored them properly. Then there's things like cucumbers or spinach that can go bad within a few days of having them in the fridge! While I was researching how long foods can last I found a website that I just had to share with all of you.
Still Tasty (stilltasty.com) lets you look up the food you're questioning and will give you information on how long it will last and sometimes even an explanation on why! I loved this because it gave me so many options, fresh, canned, packed in water, low sodium..everything was right there!
I found out opened salsa can last in your refrigerator for up to a month. They also give you tips on how to freeze your food item or how to tell if it has gone bad.
I'm of the idea that 'when in doubt, throw it out.' I know it may seem wasteful, but if you seem to be throwing away a lot of foodreconsider your grocery listor find a way to freeze portions or share with friends. I hope this tool helps!
