<<Disclaimer: Verify this information before applying it to your situation.>> Thanks, Janet and Michael, for your folow-ups on House-Autry, and also helping me to learn what questions to ask, etc. I'll look forward to whatever info Michael gets in a few weeks. Also, must show my ignorance here - the Lemon Feather Cake sounds great, but....Is "icing sugar" powdered sugar? What is caster sugar or its equivalent? Is a sandwich tin a round cake tin? And last, but definitely not least, by "potato flour" I'm wondering if Sylv means plain potato flour or potato STARCH flour.Any clarification would be appreciated. Thanks, Nancy
