Hi, I have purchased dried barberries from an ethnic foodstore where they were labelled as zeresk. I first had them in a Perisan restaurant in Paris in a delightful chicken and rice dish. The closest recipe I have found to this is 'Teheran Zeresk' which is in Claudia Roden's Middle Eastern Food recipe book. The rice is cooked in a mould with the chicken in the middle and if you can get it right you get a lovely crispy layer of buttery rice on the outside. The berries have a very sharp taste which contrasts well with the saffron/butter/chicken flavours. Jill
