Mr. or Mrs Rowdy1 goes to the St Anton church for easter and to the Conservative synagogue - where the Conservative rabbinate unfortunately officially declares allowancehalachic desecration of the Shabbat.
you are more right than me. I googled it and it'd most grains that are banned, as they are normally leavened. But leavening is not allowed, which includes yeast.
I cant see how pizza and bagels are allowed in passover, as the whole point is that the tribe was running never had time to wait for bread to rise, so you eat flat matzo based 'bread' to remember.
Normal pizza and bagels are certainly not allowed over passover. You can do a matzah-pizza of soaking matzah in some water, covering it with pizza toppings and baking it.
This isn't true. The only exception is brewers yeast because that is actually a grain (fermented barley). Wine contains yeast but wine is kosher for passover. What isn't is any fermentable grain (grains will ferment naturally in the presence of water after just under 20 minutes and so matzah is always made in less than 18 minutes).
