Regarding the three matzot (plural of matzoh), they are put in a 'bag' consisting of four squares of cloth. Picture four handkerchiefs laid together and sewn on three sides. The result is a bag with three pouches, one for each matzoh.  This is referred to as a Matzoh cover or a Matzoh tash (rhymes with "posh"), the Yiddish word for pouch.

Keep in mind that this is a Messianic Haggadah. The one Jesus (Yeshua) performed, which is still performed all over the world by non-Messianic Jews, for the most part did not refer to the Messiah.

Most of the parts that do not refer specifically to the Messiah were and still are part of the non-Messianic Seder also.

In other words, even though the Afikomen represents the sinless, broken, bruised, whipped and pierced body of Jesus wrapped in a shroud and hidden for three days, and even though traditional Jews do not believe Jesus is the Messiah, still they do those sections -- they don't understand the real symbolism of their actions.

(The stripes are caused by preparing the matzoh on a grill, because slaves on the run didn't have ovens. The flame leaves brown spots that look like bruises. Because a grill only applies heat on one side, holes are poked in the matzoh to allow more even heat flow during cooking.)

The recipies are the same as for traditional (non-Messianic) Jewish Seders. They can be found in many books and at many websites.
