Lakshmi, I loved the write-up about batter battles! I've tried just about everything. Wrapped the bowl in a sweater, placed it on a heating pad, placed it in the proofing drawer ... it's always hit-or-miss for me. The only guaranteed stuff is store-bought. DH ruins it for me by saying this about store-bought batter: If it's properly fermented, somebody's un-gloved, probably unwashed, hand stirred the batter at some point.
