Tried these at the weekend; part of our planned ‘Bread to impress’ course. The shaping is not too difficult but getting the skin forming and the chewiness is a challenge. Bicarbonate of soda is added to the water in which they are boiled and they swell a good deal in the pan and then an egg wash is applied before they go in the oven. As well as the traditional salt, I tried cumin seeds and brown sugar.
Taste and texture were good but not perfect and I think I need to make them thinner next time. Had not realised how much they swell!
