A peanut sauce should be just fine kept in a container in the fridge. Most of them contain peanuts, something sweet, soy sauce and a touch of vinegar, ginger and garlic in some combination. It will keep as there are no raw ingredients in it. There is no need to freeze it.

make a double batch ... and store the rest in the fridge. should keep about a week in a glass jelly jar or such.

I would wager a bet that it will. keep way beyond a week. It has acid, sugar and salt, much the same as does something like ketchup or bottled salad dressings.

How would one determine that it did not "keep"? By what measure other than maybe some mold, would it be determined? And, that is unlikely to happen in any reasonable time frame, if at all.

Lar's suggestion to add the peanuts when you use it is probably a good idea if you are really intending to keep it a while before using. . As he pointed out, they can get soft and you want that crunch and texture.

Yes! I do it all the time. You just need to remix well when you thaw it. My recipe is p-nut butter, coconut milk, garlic onions, etc. and it is fine defrosted.

I would also think you could store it in a bag and press it flat and freeze, might make it easier to break off a piece for use. I use dry roast peanuts and turn them to dust.

Daisychain the recipe I want to try has peanut butter rather than peanuts also.

Bragu thank you I've done that with the flat bag and pieces for larger quantities of stuff I wanted to freeze, but for small quantities of dips I have 2 ounce plastic disposable containers with covers.

I finally made it yesterday Made a quart and froze it in 2 oz cups. I had to tweak it a little to suit my tastes, I added a little more lime juice. It is delicious, and the air fryer did a good job heating and crisping up the egg rolls.

Next time I would like to use actual crushed peanuts and see how that compares with the peanut butter. But when I did a search for peanut sauce all that came up were peanut butter variations.

Lucille, good peanut butter has only two ingredients, peanuts and salt, Such products ARE actual crushed (or ground) peanuts and really nothing else. Besides biting off a bit more work, I don't think you'll find using crushed peanuts will make much of a difference.
