I made a commercially-yeasted pizza dough about a week ago, but in all the viral circumstances, I’ve kept it in the fridge, as one might do with a sourdough. If I want to use it, does it need reviving, is it spoiled, is it becoming a sourdough if I “feed” it"?
I did that. I made far too much yeasted dough last Saturday, and stored it in the fridge, taking out just enough for a loaf every couple of days and a pizza crust. It still rose well yesterday. There was a cup left over, so I mixed it with some more flour and water at a 5:3 ratio, and added salt. This took a few hours to get started, much longer than the Saturday batch, but it did double in size eventually. I put it in the fridge to slow-proof, and I’ll make more bread tomorrow morning.
I didn’t. This was an experiment in propagating the older batch as a “mother” to the new batch. I just set a loaf out for a final rise, and we’ll see in a couple of hours whether it worked.
Success! The dough was a little wet, and so spread out in the baking tin, but it rose well enough for a good crumb. So, that’s the ticket for now, reserve a cup or so of dough and mix it in with fresh flour, water and salt, let it proof overnight in the fridge and then rise for a couple of hours in the baking tin.
I’ve found that there are two meanings for “proofing”, when you dissolve active dry yeast in a little water and maybe a little sugar or honey, and let it sit for 10-15 minutes until it starts to bubble, and as a synonym for rising after the ingredients, including salt, are mixed. I meant the latter, just a long and slow rise in the fridge.
That dough I made back in April lasted until about a week ago. I reserved some of the dough from each batch and used it to make subsequent batches. It finally petered out after a month, and I started again with another packet of instant yeast (which doesn’t need proofing in the first sense of the word). I lucked into a regular source of yeast from our local hippie bakery, so I’m all set, going forward.
The first is a good way to always check that your yeast is alive.
I think it also activates it faster than tossing the whole lot of ingredients together a la the no knead recipes I tend to favor. Maybe it’s in my head, but I think I get a better outcome when I do vs when I don’t.
