Baked to sheer perfection and beautiful with a cup of tea (500g) Since 1939, Ouma rusks have been a trusted household name in South Africa. Ouma originated when Ouma Greyvenstyn started making and selling her famous homemade rusks using her trusted family recipe on her farm in the small North Eastern Cape town of Molteno. Made from a time-honoured family recipe, Ouma rusks are baked to sheer perfection.
