EMILY: Now, we have eggs, fruit, toast, pancakes, blintzes.
Blintzes are a variant of the Russian pancakes called blini – they are thin wheat pancakes folded over to form a casing for a filling (such as fruit, jam, chocolate paste, or cheese), and then sauteed or baked. The word blintz is Yiddish, possibly derived from Ukrainian.
Blinis are a traditional food in Slavic countries. In pre-Christian times, they were served at the end of winter to celebrate the rebirth of the sun (I guess because they are round and yellow-ish, like the sun). This tradition continues in the Orthodox church, as the timing fits in with the start of Lent, when people are encouraged to eat up all their butter, eggs, and milk – foods forbidden during the Orthodox Lenten season.
Blintzes were introduced to North America by Jewish immigrants from Eastern Europe. They are traditionally served on holidays such as Hanukkah and Shavuot (a spring festival).
As blinis and blintzes are traditionally eaten in spring in Paganism, Christianity, and Judaism, it makes sense that they feature in an episode set in April.
