Hi,

I had a batch of yogurt come out with a "gritty" texture. What can cause
that? I made two quarts of yogurt in a 2 quart beverage cooler from
powdered milk. I scalded the milk by heating the water and then added the
dry milk to the hot water (I thought there would be less chance of scorching
and I could heat the water quickly). I didn't notice anything peculiar when
I put the yogurt into smaller containers and put them in the refrigerator. I
left the containers open in the refrigerator to cool faster for about an
hour. The next day when I ate some I noticed parts of it had a slightly
different appearance and had a gritty texture.

The particles had the consistency of cheese. Could the yogurt have dried out
while cooling uncovered in the refrigerator? I've read about cheese made by
draining the liquid out of the yogurt.

The only thing I did differently from previous batches was to heat the water
first and add the powder to the hot water rather than mix the milk and then
heat it. I don't think the grains are undissolved powdered milk.

Any ideas?


Thanks
