Is it obligatory to give sadaqah al-fitr as wheat, barley, date, or grape?

Sadaqah al-fitr may be given both in kind of the food items mentioned in the question and in cash of the equal value. However it is more appropriate to choose the method that is more benefical to the poor. (Ibn Abidin, Radd al-Muhtar, III, 321, 322).
