To all of you who replied with really helpful suggestions, thanks very much. Some of the things you suggested, I can do. Others (like pasta dishes and anything with sesame), I cannot, because there are some allergies and other dietary restrictions in my family (among all the people who will be here for yom tov),that make some of those delicious sounding suggestions undoable for me, unfortunately. (I commiserate with those whose ovens also broke down). My neighbor graciously allowed me the use of her oven today, so I am trying to do what I can this morning. I HATE going into yom tov with stress.
I have a wonderful repair man, whom I trust implicitly, and he cannot get the part needed. The thermostat on my old Magic Chef wall oven, went. They do not make this type of thermostat anymore. The oven was valuable to me because it had a continuous pilot (not electric ignition).
Convection ovens that run on electricity, will be good for before yom tov, but won’t help on yom tov. I cannot get a new oven installed before Shavuos, in any case, even were I able to afford one. But now the question is, any recommendations for wall ovens???? Pros and cons…
