guys guys guys!!!OVERNIGHT KUGEL!!
After you finish baking your kugel in you usual method, leave it in the baking pan and you wrap the potato kugel very well in silver paper. Place a different pan of water underneath it and keep it in the hot oven from Thursday night through Shabbos afternoon (and yes, you can cheat some on Friday afternoon and evening).
You shall bless me for this. I promise.
