I turn my kitchen over in term vacation time. I prepare all the side dises.. charosess, kugels, cakes icecreams, etc…etc.. I turn it back over to chametz and just a few days before pesach I turn it back into pesaach mode again. I have done this before just about every year… and I find it very affective. that way it’s not an overwhelming last min job. I like everything to be perfect. evth that I prepare goes into the spare freeezer.
my house is pesach cleaned practically all year round. I just give it a good spring clean and were all good! I also like to wash my pesach things, tablecloths, tea towels, afikomen bags..etc.. mid year so that they don’t smell musty from sitting in the cupboard all year come pesach.. and I polish all the silver 3 times a year so I don’t have to worry about it so much last minute.. come seder night everything is sparkling sqeaky clean. I love it!
