I make a little at a time and store it in a clean glass container in my fridge. You can also make it in large quantities but make sure to use it up soon as the shelf life of this is less compared to the store brands. I also use a fruit-juice-sweetened-no-sugar-added jam and whole wheat bread to make these sandwiches. Maybe next time I will try to make my own jam and whole wheat loaf too !!
If you use salted peanuts, do not add any additional salt. You can also use honey roasted peanuts, in that case skip the honey. Some recipes called for some peanut oil to be added , however I skipped that as peanuts do have peanut oil in them.
