If you are going to eat it up, in the week you make it you should be fine. It could be set in the frig.
I am still not sure of your question. Or I am just plain dense today.
You made a batch of sauce ? You canned it in the water bath
with regular jars, and your lids did the *ping* so you know you got a seal. Correct ?
Then it should be fine. Not sure what else you put in the sauce.
If meat.....then it should have been pressure canned.
I bought a pressure canner this summer at a garage sale for $3 to use as a back up canner. I still have to buy a handle for the cover as the one is missing. Also the weight is missing so will have to buy that and not sure why but my other 2 canners, I can't borrow the parts from. One canner is my mom's and very old, and they don't make gaskets for anymore, so would only use that as a emergency one. My main canner I bought years ago, at a garage sale for $ 5.
Have you been on craiglist or freecycle checking out things ?
I picked up the blue book the other day in Walmart and glanced through it, and put it back down. I thought it was just me who was not impressed..........
