Maddy, I have just seen a great tip to stop the condensation dripping back on to the food. Place a length of paper towel across the varoma before putting lid on to steam. It was from Alyce Alexandra's cheesecake video on Super kitchen machine website ( sorry, I don't know how to link!) I got it as an email and can forward it on to you if you would like.
Hi kt2 - here's the youtube link for Alyce's steamed cheesecakes . . . http://www.youtube.com/watch?v=93j2N9nv1VEthe tip about the paper towel is at around 6.35 more towards the end
Maddy you are such a gem, I know you will perfect them.
