it will be delish, send me a slice. sugar may take a bit longer to dissolve however but will have an even nicer taste that white. I do orange drizzle too sometimes with brown sugar mmmmm sandwiched with marmalade too. <no wonder I am fat>
I went for it and it was delicious! I think it is actually even better than the lemon version, although the topping is less crunchy. DD was completely converted too, and DH said it was the best cake we'd ever made (mind you, he has had to put up with some dire, pancaked burnt offerings in the past).
