I picked up an absolutely awesome recipe for Boston buns in the weekend. It was my husband's great auntie's recipe from the War ration era.
You can make one large round, or I make a dozen smaller individual buns.
3/4 C sugar
1 C cold mashed potato
2 C flour
2 tsp Baking Powder
1/2 C milk
1/2 C sultanas
Cinnamon to taste(optional)
Cream potato and sugar together in food processor or cake mixer. If lumpy sieve until smooth.
Add rest of ingredients and mix to form dough. Shape into large bun (or smaller ones). Place on lined baking tray.
Cook for 30minutes at 160 degrees Celsius. Takes about 15min for smaller buns.
Cool, then ice with pink icing and coconut.
