Milk and honey, greenery and harvest — the gift of the land beside the gift of the Torah.
On Shavuot it is customary to eat dairy — cheese, cream, blintzes, cheesecake. The Torah is likened to milk and honey: “honey and milk are under your tongue” — so sweet is its taste.
There is also a simple reason: having received the laws of kashrut at Sinai, the people had no time to prepare meat by the new rules — and that day they ate dairy. So the custom reached our tables.

Shavuot is a harvest festival. Home and synagogue are adorned with greenery, and in earlier days the first fruits of the land were brought to the table.

Bikkurim: in Temple times, on Shavuot the first fruits of the seven species of the Land of Israel were brought — in thanks for the harvest.
Shtei HaLechem: in the Temple a special offering was brought on this day — two leavened loaves from the new wheat harvest.
