For how long...

...can I keep peanut butter and maple syrup after they've been opened?A friend brought me huge(I mean huge!) jars in june.They're half empty now(or half full if you're optimistic!).I'm in Brazil,it's almost Spring here but it's so hot it feels like Summer,so they're in the fridge.It's impossible to find maple syrup in Brazil.I would hate to see it go bad,so depending on your answers maybe I'll use it for something other than just breakfast.

Maple syrup can keep "forever" in the refrigerator. The high sugar content well preserves it. The danger is from mold which can grow in the moist environment. Be careful not to contaminate it and watch for any obvious signs of growth. Otherwise, enjoy!

Peanut butter "best by" dates assume RT storage. You can extend that considerably in the fridge. Low in moisture but high in unsaturated fat, the danger is oxidization. Oxidization = free radicals = cancer. A year is reasonable I think. In any case, *before* it tastes stale.

Unless it's maple syrup straight from a tree to te bottle you should be fine. B/c all maple syrup needs to be pasteurized. If it isn pasteurized simply boil it and add a few table spoons of water and you'll be ok. And if refrigerated the peanut butter will be fine. And no maple syrup in Brazil? You might the most popular person in town.

As long as you keep them in the fridge, both of them wil keep until you use them up -- literally forever.

@BillF: since real maple syrup is made by boiling down maple sap until the sugars concentrate, it's all pasteurized at the point of production. It is literally impossible to buy real maple syrup which is not pasteurized.

On peanut butter I'd be less worried about it's age than about salmonella. Another recent outbreak here in the states. I'm not sure which label.
