(and once daily until it starts to expand and smell yeasty), mix . . .
2 oz. of the starter (1/4 c. after stirring down–discard the rest)
1 oz. flour** (scant 1/4 cup)
1 oz. water (2 tablespoons)
** You can feed the starter/seed culture whatever you would like at this point. White flour, either bread or a strong all-purpose like King Arthur or a Canadian brand will turn it into a general-purpose white sourdough starter. Feed it rye flour if you want a rye sour, or whole wheat, if you want to make 100% whole wheat breads. If you’re new to sourdough, a white starter is probably the best place to start.
Overnight activity has been noticed. In fact, at about 1 a.m., PJ had already doubled and was on the way back down so he got a midnight feed. Come feed time again today, he had once more doubled (where the dashed line is) and gone back down. Wally, on the other hand, has developed small bubbles and expanded just a wee bit. He still stinks although not quite the “OMG YUCK!” strength as before, he’s decidedly unpleasant.
After yesterday’s feed. the starters both began to expand (up to the purple line) Wally had a pretty good rise this time, too; he seems to be catching up quite well. We may be just one or two feeds away from finishing the project. PJ is clearly well under way.
Both starters were pretty much done expanding within three or four hours before they started to collapse. This means they went for the remaining 20 or so hours “unfed”. They had, in effect, chomped through whatever food they were going to in rather short order. You can even see in the photo a very slight layer of liquid on top of the starter. This is “hootch” and it’s a normal byproduct of our friend the Lactobacillus sanfranciscensis when a starter is ‘hungry’. The solution? Feed it.
Here we are at Day Seven, just a tad past 7 a.m., last day of the one week run (although we technically don’t start day 7 until 3pm and we’re therefore in the tail end of day 6) and our starters are hungry.
