Kosereva
Kosereva is a Paraguayan home preserve from the days when nothing was wasted: thick strips of bitter-orange peel soaked and boiled to soften their bite, then cooked slowly in dark cane molasses until glossy and nearly black. In the countryside it is eaten after lunch with a slice of fresh cheese or simply on its own. Bitter oranges (Seville oranges) are in season in winter. The most common mistake is not changing the boiling water enough, which leaves the peel unpleasantly bitter. Chef's tip: taste a sliver of peel after the third boil; it should be gently bitter like marmalade, not harsh.
