RE: Double Chocolate Muffins - Not Great!

I spent half the evening reading articles on rubbery sponge! The wife thinks I'm mad. You are correct, though, almost every spongy thing in Thailand is poor. I read it could also be down to the amount of proteins in the flour. I'll try again using exactly the same recipe when I'm back in the UK next month. This is becoming an obsession!
Hope you and Mum are doing well and have a great weekend :-)
