Called Jewish wontons or raviolis, kreplach are pasta dumplings, usually triangular in shape, filled with minced meat, onion-spiced potatoes, or cheese. Kreplach carries a lot of lofty symbolism; its triangular shape represents Judaism's three patriarchs: Abraham, Isaac, and Jacob. Equally lofty: the Jewish momma who can roll her kreplach dough to optimum thinness (so that, according to Sam Levenson, "a tempting bit of their buried treasure should show through"). If the wrappers are not paper-thin, your kreplach will taste like "craplach." However, though we've included wrappers in this recipe, there's really no reason to knock yourself out making them. Just purchase wonton wrappers in a Chinese food store or supermarket, and making kreplach becomes a cinch. There's even a kosher brand called Nasoya, available in many supermarkets; look for it near the tofu.
