newbie ? - bread not rising
I am very new to baking, and I'm running into a problem. My dough seems to not be rising after i mix the ingredients. I can't tell if the yeast is bad (i've been keeping it in the fridge in a ziplock baggie) or if my kitchen is too cold (I'm in north Texas with highs in 50's and the heater running keeping the house between 65-73 throughout the day).
I can't figure out if it's to cold or the yest has gone bad......
any help would be appreciated.
