Numbers 11:7

The manna is like coriander seed. The one who said this [verse] did not say the other. The Israelites said, ‘Nothing but the manna before our eyes.’ while the Holy One, Blessed is He, inscribed in the Torah, “But the manna was like coriander seed, etc.,” as if to say, ‘Look, those who walk the earth at the subject of My children’s complaint — the manna was precious for such and such a reason’.

Like coriander seed. Round like coriander. “Aliendre” seed in Old French.

Crystal The name of a precious stone, “cristal” [in Old French].

Alas for the people whose food is bread from the heavens! And so murmured they, because the manna was like coriander-seed, round, when it came down from the heavens, and when it had been sanctified its appearance was as the likeness of Bedilcha.

והמן כזרע גד הוא, whereas its appearance was like that of crystals. In other words, whereas in fact it was soft inside, it appeared hard from the outside. When looking at it the people said ונפשנו יבשה, “we are completely dried out, like someone who has to eat hard and dry kernels of wheat. If so, why did G’d become angry as we are told in verse 10?
Now the Torah explains the reason for G’d’s anger. When the people would grind the manna crystals in their mortars or mills, its taste was like something creamy, oily. This taste which originally had been described as similar to crackers smeared with honey (Exodus 15,31) changed to be like nuts after they are ground. After undergoing grinding it now became moist and like an oily substance. Seeing that it did not taste dry at all, the people’s complaint was unfounded, and this is why G’d became angry at the unjustified accusation that the manna was the reason that their whole system dried out. In Beshalach, where the taste is described as a wafer smeared with honey, the Torah spoke about what the manna tasted like raw, in its original state, prior to assuming the taste of rich cream.
