Working magic with food prepDear Heloise: I have a question about cooking foods at different times and temperatures when you only have one oven. I really don’t like to cook ahead and microwave food, but this seems to be the only option. This is what I have done in the past:I cooked the main dish first and placed it in the microwave to keep it warm. When it was done, I placed the main dish in the oven to keep it warm. — HeloiseSEND A GREATHINT TO:Heloise@Heloise.comREADING ENJOYMENTDear Heloise: In response to Marvin Tiffany, in York, Nebraska, at 81 years of age, I, too, prefer a physical newspaper before breakfast.
