Is Matzah supposed to taste good? (or "is matzah pizza 'kosher'?")

You shall slaughter the passover sacrifice for the LORD your God, from the flock and the herd, in the place where the LORD will choose to establish His name. You shall not eat anything leavened with it; for seven days thereafter you shall eat unleavened bread, bread of distress [lechem oni]—for you departed from the land of Egypt hurriedly—so that you may remember the day of your departure from the land of Egypt as long as you live. For seven days no leaven shall be found with you in all your territory, and none of the flesh of what you slaughter on the evening of the first day shall be left until morning.

And they baked unleavened cakes of the dough that they had taken out of Egypt, for it was not leavened, since they had been driven out of Egypt and could not delay; nor had they prepared any provisions for themselves.

Rabban Gamliel would say: Anyone who did not say these three matters on Passover has not fulfilled his obligation: The Paschal lamb, matza, and bitter herbs. When one mentions these matters, he must elaborate and explain them: The Paschal lamb is brought because the Omnipresent passed over [pasaḥ] the houses of our forefathers in Egypt, as it is stated: “That you shall say: It is the sacrifice of the Lord’s Paschal offering for He passed over the houses of the children of Israel in Egypt, when he smote the Egyptians, and delivered our houses” (Exodus 12:27). Rabban Gamliel continues to explain: The reason for matza is because our forefathers were redeemed from Egypt, as it is stated: “And they baked the dough that they took out of Egypt as cakes of matzot, for it was not leavened, as they were thrust out of Egypt and could not tarry, neither had they prepared for themselves any victual” (Exodus 12:39). The reason for bitter herbs is because the Egyptians embittered our forefathers’ lives in Egypt, as it is stated: “And they embittered their lives with hard service, in mortar and in brick; in all manner of service in the field, all the service that they made them serve was with rigor” (Exodus 1:14). The tanna of the mishna further states: In each and every generation a person must view himself as though he personally left Egypt, as it is stated: “And you shall tell your son on that day, saying: It is because of this which the Lord did for me when I came forth out of Egypt” (Exodus 13:8). In every generation, each person must say: “This which the Lord did for me,” and not: This which the Lord did for my forefathers. The mishna continues with the text of the Haggadah. Therefore we are obligated to thank, praise, glorify, extol, exalt, honor, bless, revere, and laud [lekales] the One who performed for our forefathers and for us all these miracles: He took us out from slavery to freedom, from sorrow to joy, from mourning to a Festival, from darkness to a great light, and from enslavement to redemption. And we will say before Him: Halleluya. At this point one recites the hallel that is said on all joyous days. Since one does not complete hallel at this point in the seder, the mishna asks:

Shmuel said that the phrase: “The bread of affliction [leḥem oni]” (Deuteronomy 16:3) means bread over which one answers [onim] matters, i.e., one recites the Haggadah over matza. That was also taught in a baraita: Leḥem oni is bread over which one answers many matters.

One time I was walking on the way. A man found me, and went with me on the way of mitzvot, and he had mikra (ie: written law) but no mishnah (ie: oral law). And he said to me, "Rabbi, mikra was given to us from Mount Sinai. Mishnah was not given to us from Mount Sinai." And I said to him, "My son, mikra and mishnah were both of them said from the mouth of God." And what is the difference between mikra and mishnah? Rather he told him a parable: To what is this matter similar? To a human king (lit: a king of flesh and blood) who had two servants, and he loved them with a great love. And he gave to one a kab (a measure) of wheat and to the other kab of wheat. And he also gave to each one of them a bundle of flax. The wise one of them took the flax and wove a beautiful cloth, and took the wheat and made it into fine flour, and sifted it, and ground it, and kneaded it, and baked it, and set it on the table, and spread the beautiful cloth over it, and left it there until the king should come. And the fool of them did nothing. After some time the king came into his house, and said to them, to his two servants, "My sons, bring to me what I gave you." One of them brought out the bread of fine flour, on the table, with the beautiful cloth spread over it. And the other of them brought out the wheat in a pile and the bundle of flax upon it. Woe for that shame! Woe for that disgrace! Which one is more favored? You must admit it is the one who brought out the bread on the table with the beautiful cloth spread over it.
