My granny's recipe for a super fluffy apricot jam roulade (sponge roll). With video instructions.
If the roulade is not filled with jam, but with something that should remain cool (eg. cream cheese filling), then do not sprinkle immediately after baking. Cover the roulade on the top with another baking paper and roll it without filling. Let it cool. Then carefully roll out again, remove upper baking paper. Brush with filling and finish rolling.
