Default Starter math problem

Hello all

I did some baking last weekend. I fed 250 grams of starter with 250
grams of flour and 250 grams of water and let it work overnight. I
wanted 250 g each for the bread recipe, the starter pot and for
pancakes the next day.

The next morning I found I had barely 650 grams. I had to add 50
grams each of water and flour to have enough for the pancakes.

When I went to school 250+250+250=750, so what happened to the extra
100 grams?

Howdy,

It was metabolized by the critters and escaped as gas...
(also, some of the water evaporated.)

All the best,

If you are using a digital scale, have you checked it for accuracy? I
followed a recipe once with a Salter scale and judging by the dough, it was
waaay off. I then noticed that I had set the scale over the right-angle
join in the counter top and the distortion caused by the laminate resulted
in an uneven surface for the scale making it weigh incorrectly. After that
experience, I always check by weighing up to 3 loonies (7 grams each) before
weighing the flour etc.

Thanks for that, Kenneth. It makes sense, but what's surprising is
the magnitude of the change. Wow. a 13% drop through release of a bit
of gas and water vapour.

Hi to a fellow Canuck.

It is a digital scale but I used it on a hard flat surface. Good idea
to use loonies as a check, though.

Thanks.

As a Calgarian, your problem might be due to the inequalities that our govt
maintains between our two cities{;-)

I was gobsmacked by that stupid decision! Mind you, I think Edmonton

Hi Mike,

I am surprised by the loss every time I measure it (and have
been for about 40 years.)

All the best,

I completely agree. Now is the time to be conserving resources, but
then our mayor is a bit of a spendthrift when it comes to left-wing or
artsie-fartsie projects.

The trouble is, these "projects" come from the business sector and are then
passed over to the govt to promote. The Calgary Olympics were such. They
keep saying that the business men who ended up running the show made a
profit of 200mill, forgetting that the Feds and Alta govts put 200mill into
the pot to build the facilities in the first place.
