I just think it's hilarious how so many recipes begin with "Preheat oven to XXX degrees" and then continue with a very long list of preparations that must be completed before the item goes into the oven. As if getting your oven to the correct temperature took much longer than the usual 5-10 minutes and was more complicated than simply twisting a dial or two. As if preheating the oven involved something like felling trees and chopping them into kindling, maybe rubbing sticks together to create fire. Yesterday I was following the recipe on the back of a box of lasagna noodles to try a new type of lasagna. This is a dish that requires the boiling of pasta, the browning of meat, the assembling of several other ingredients first before the rather elaborate task of layering them into a baking dish. Yet the first thing the recipe mentions is "Preheat oven to 375 degrees". If I had done that first, the kitchen would have been sweltering and a lot of electricity would have been wasted in keeping the oven so hot for so long before necessary. I know that it's important for some recipes to have the oven already at the correct temp before putting the dish in to cook. But good grief, give us folks some credit! Mention heating the oven near the end of the recipe, especially for dishes that take a long time to assemble. This time I started the oven when I was in the middle of assembling my lasagna layers and it was hot enough by the time I finished. When do YOU turn on the oven for cooking?
