Flour-to-matzo meal equivalents

As a sort of seasonal question to add to Stephanie's matzo ball discussion, does anyone know how much matzo meal to substitute for flour when using/converting regular recipes for Passover? These would be recipes in which flour is more of a binder or thickener, rather than a main ingredient (e.g., not cakes, but maybe something like Yorkshire pudding). Thanks, and to all, a happy and healthy Passover!

Here's a list of substitutes:

For 1 ounce baking chocolate (unsweetened chocolate) -- 3 tablespoons unsweetened cocoa powder plus 1 tablespoon oil or melted margarine

For 16 ounces semisweet chocolate -- 6 tablespoons unsweetened cocoa powder plus 1/4 cup oil and 7 tablespoons granulated sugar

For 14 ounces sweet chocolate (German-type) -- 3 tablespoons unsweetened cocoa powder plus 2 2/3 tablespoons oil and 4 1/2 tablespoons granulated sugar

For 1 cup confectioners' sugar -- 1 cup granulated sugar minus 1 tablespoon sugar plus 1 tablespoon potato starch pulsed in a food processor or blender

For 1 cup honey -- 1 1/4 cups granulated sugar plus 1/4 cup water

For 1 cup corn syrup -- 1 1/4 cups granulated sugar plus 1/3 cup water boiled until syrupy

1 cup vanilla sugar = 1 cup granulated sugar with 1 split vanilla bean left for at least 24 hours in a tightly covered jar

For 1 tablespoon flour -- 1/2 tablespoon potato starch

For 1 tablespoon cornstarch -- 1 tablespoon potato starch

For 1 teaspoon baking powder -- 1/4 teaspoon baking soda plus 1/2 teaspoon cream of tartar; if keeping for awhile, add 1/4 teaspoon potato starch (some people do not accept this as appropriate for Passover)

For 1 cup graham cracker crumbs -- 1 cup ground Passover cookies or soup nuts plus 1 teaspoon cinnamon

For 1 cup bread crumbs -- 1 cup matzo meal

1 cup matzo meal = 3 matzot ground in a food processor

1 cup matzo cake meal = 1 cup + 2 tablespoons matzo meal finely ground in a blender or food processor and sifted

3 crumbled matzot = 2 cups matzo farfel

For 1 cup of flour, substitute 5/8 cup matzo cake meal or potato starch, or a combination sifted together

Just what I was looking for! Thanks, Nancy!

I know my memory is rusty, but what is not kosher-for-Passover about chocolate? I'm confused. What is the context of this list? (although it's pretty informative- thank you).

Any prepared food must be specifically kosher for Passover. Most chocolate is not KFP (some contain vanilla extract that contains alcohol (alcohol products must be specifically KFP,) some contain soy derivatives) and KFP chocolate is not readily available in some areas of the country, so this list contains an appropriate substitution.

If it's binder/thickener you want, see if you can get some potato starch. I believe you can use that the same way you'd use flour, in the same quantities.

Thanks! I've never used potato starch, and hadn't thought of it. I'll give it a try.
