Make Challah

Supply chain meltdowns must have caught up with the usual mini-challot that I buy as a six-pack every three weeks.  Shop-Rite had lots of whole challot but no minis.  It doesn't help that only one brand seems to make them for sale here.  That leaves me to make my own for shabbos dinner.  I like making challah but recipes call for too much and they are hard to apportion downwards.  My attempts at challah knots have not been very good and likely won't freeze as well as commercial Zomick's which hires or contracts with food scientists to determine additives for enhanced usable life.  Just scale back the loaf ingredients as best I can.  Challah recipes tend to be pretty flexible anyway.
