Note that the original recipe did not contain weights or measurements for ingredients. They used one glass to measure everything. So to give you an idea, they used a slightly narrow, short glass and measured as follows: 1 glass yogurt, 3 glasses of flour, 2 glasses of sugar and 1 glass of oil. I tried to use a similar sized glass and measured/weighed them to come up with my quantities.
Butter and flour a bunt pan or ciambella pan. Mine is 26cm in diameter. Baking times may vary depending on the depth and size of your pan.
