Well, it's about 72 hours after I started and the curd has been in and out of the fridge a few times. It finally got fairly stretchy although I think it would have gotten better with a bit more time.
I cut it into curds and added hot water (I wasn't sure if the whey was still good) and it sort of melted, not super soft but stretchy enough to pull it up a foot or so above the bowl without it breaking. I worked it into a lump and then pulled off small balls and put them in salted cold water.
I've tried them, they are very rubbery, and a bit squeaky. Not terrible but not at all soft. I'm sure I overworked the curd terribly trying to get it melted and stretched.
What is the right culture to use? Will just buttermilk do it? I'm not sure but I've read that on here as well. If so, how much?
I'm going to try another batch this week and see what happens.
Any and all advice would be appreciated.
