Bogobe jwa lerotse, also known as slap-pap, is a type of porridge eaten in Botswana and also a national dish of Botswana, characterized by a delicate flavor imparted by the lerotse melon, a type of fruit that is visually reminiscent of a typical watermelon and distinguished by its orange-colored flesh. Lerotse has a neutral flavor when raw, but it imparts a unique flavor to the dish when cooked. The dish is typically stirred with a traditional wooden whisk, called lehetho, and has a porridge-like consistency when fully cooked. It is often consumed at weddings and other social gathering.[1]
Its key ingredient is the lerotse melon, a less-sweet variety of watermelon indigenous to Botswana which is more similar in taste to the cucumber when raw.[2] Along with the lerotse, which is chopped into pieces and boiled, the dish includes sorghum meal and sour milk.[1][3]
