Fresh yeast will melt and eventually foam on top of the water. My bread is always perfect because I use my machines as mixers and then shape my loaves or rolls and then bake them in my oven. By the way I have been making bread for over 40 years. I used to use it to make bread dough, put in my breadpans and bake. First, one cannot be too careful with the salt.
Anytime salt comes in contact with yeast,less than desireable results occur.
We had a DAK before it wore out and always had good results. Best of luck. The flour must be on top, and then make a dent or hole in the flour for the dry yeast. The yeast has to mix with the flour first because yeast does not like to mixed with salt. I forgot that important fact in my first letter.
