I have separate dishes, and buy only foods that are marked. It has gotten easier over the years as more companies have jumped on the bandwagon. I always promise myself that we will eat as close to normal as possible. I try to have more fruits and vegetables around the house. Salad as a meal. My kids are hoping to lose a few pounds...
But the costs... Yeah, it is prohibitive. It's a shame that the cost of koshering your house should be a burden, but that is what it has become! I am having 16 people, and I make a soup with flanken and chicken. The soup, alone, will cost over $100! That just seems ridiculous!
The most fun part for me is preparing "decorations". I have been making name cards for everyone, and this year I made some rubber stamped and scrapbooked cards. They came out great, but the guess list keeps changing! My son is in college and invited a few kids that didn't have a place to go. Not knowing their names I just put the school name on their cards.
While the cost of pulling this off has left me unable to buy any "extras" this week, I am enjoying part of the process.
