I plan to take a frittata to a relatives Christmas party on Saturday.
Should I mix everything together, and bake at her place (which in the
past verged on chaos). Should I cook it at home and, then just warm it
up at her house. It might be about six hours between cooking and
warmup. The high temps in the area will be around 26 degrees F, so I
do not think it would spoil. Should I just mix the eggs together, and
add everything else (cooked sauage, scallions, cheese, and mushrooms)
when I get there, and then bake.

Thanks

Tom
