Pastry substitute

I teach breadmaking (around 10 hours a week, ATM) – and each session only lasts two hours from start to finish. I run two sorts of sessions; one for adults with learning difficulties, where we make different breads each week; and regular 5-week courses - for parents and children in a local primary school (Family learning); and community evening classes for the general public, where the content is fairly well structured (each course has a session on loaves, rolls, pizzas, etc.)
