Pepper Jam recipe with pepper in weight
As always thanks in advance for any info, I really appreciate it!
I am using already chopped frozen peppers to make jam. Most recipes I see call for either cups of chopped peppers or a certain amount, like 4 chopped peppers. Now, peppers vary in size, and once frozen and if thawed at all, they compress so that 4 cups of thawed peppers will be more than 4 cups of fresh cut peppers. Does anyone have a safe recipe that uses pounds rather than cups?
Alternatively, is there a formula for x pounds of low acid ingredients need x cups of vinegar to acidify safely for jam?
If I used 1 1/3 pounds of peppers would 1 cup of Apple Cider Vinegar and 5 cups of Sugar be safe?
Finally, I do not blend my peppers such that there is a variance in how many peppers are in each jar, I try and even it out but sometimes jars get more peppers and sometimes less when I pour in the jam. Could this pose a safety risk?
Oh, one more question. If I make jam and refrigerate (not process in BWB) is there a general rule for safe refrigerated shelf life (6 weeks? 2 weeks?)
Thanks so much!
