Its name comes from crépon, a crinkled fabric, a nod to the fine, frosty texture that whipped egg white gives the lemon ice.
Créponné is a lemon sorbet whisked from beaten egg whites, sugar syrup infused with lemon zest, and fresh lemon juice, churned or hand-beaten until light and airy. Vendors and corner shops across Oran sell it in cups during the hot months as an icy, tart refresher.
