How can I tell if water is warm enough for yeast?

You can always put your wrist, not just the hand in the water as it is running. Like the other person said, like baby's bath water. If it is comfortable to the touch, not too hot, the yeast will comply nicely. They are not that fussy unless too hot. If you like a homey crust, you can also use Rhode's dough from the freezer, ready made and convenient, just thaw. Sometimes you can find the soft dough in your grocer's cheese and deli section ready to go. I use this type a lot! Less stickiness on the fingers, less time to rise and punch down. But I give you the thumbs up for being the kind of person who takes the time to make it homemade! Very good! When's dinner?.........:D...>(8>)=

I usually get hot water out of the tap and get things ready. By the time I have everything out, mine usually is around 110 degrees.

I always whisk my yeast into 1/2 cup of water and let it proof. I then add the rest.

I also use bread flour for pizza crust. I used to use regular, but tried it out just the other day and it was fantastic... won't go back to regular.

110 Degrees Fahrenheit

A little warmer than baby bath water is what I use, and I have no problems. Above poster is wrong, it needs to be about 110.
