A pot or pan that has not been used for leaven for the last 24 hours is נותן טעם לפגם and"gives a damaged taste." From the Torah one can use it. (But דרבנן it needs boiling).
The top of a stove needs nothing because every time you use it, makes it OK. [Not to mention the inside of an oven which needs nothing at all in the first place.]
The best way to make unleavened bread is to buy flour and water and mix it and fry it like a pancake. The major thing to be careful about is to do it immediately. Once water and flour have come into contact with each other you have 18 minutes left to cook or fry it. However, the mix must be thick to be thought of as bread; and to use only a little oil on the bottom of the pan. Otherwise it is cake.
[Another reason not to use oil is a molecule of oil is hard to break down. It can cause over strain on the intestines.]
15 days from the new moon turns out to be Friday night.[The calendar people use was invented by Meton in Athens, and is not from Sinai. And it is usually off by a day or two.]
Night starts 72 minutes after sunset [to the vast majority of Rishonim] The beginning of twilight is 58.5. [You might be strict to stop work after 45 minutes because in Israel it looked to me that that was about when middle stars became visible. However in the Rocky Mountains and in the mountains around Southern California it looked to me that stars kept coming out even much later--until the middle of the night the sky seemed to be much more filled with stars than around 90 minutes. So you might rely on doing work until 58.5 minutes.]
For wine the best idea is to buy grapes and get one of the small crushers that are used for garlic. But this takes a good long time to get up the volume. One cup is the size of 1.5 eggs.;which means one needs the volume of 6 eggs. [If one does not have enough grapes for that he can do מזיגה --put in water.] [The amount of water you can put in and still have the blessing be Pri Hagefen is astounding; one part wine, 6 parts water.]
It is best to do everything yourself and to buy nothing but grapes, flour, and horseradish, nuts and raisins.
