Does anyone recall how spectacular fresh yeast is? Especially in a challah? Fresh yeast is available from local bakers or by Fleishmanns (look in the dairy case). Whatever you do – find a way to find it! It makes the best challah possible – it even smells like a old fashioned, real bakery – in your kitchen- just as it is rising (never mind when it bakes and is ready!) You can also let this rise about 20% and then freeze the dough/loaf. Let it rise in the fridge the night before baking and give it 1-2 hours on the counter before actually baking it.
