I'm so glad to made you remember this lovely bread my friend! It is really very easy to make and i am sure you'll do it perfectly!
I have never tried another type of flour yet, but I do think spelt flour should work also. As for the addition of some other ingredients, yes of course you can. Caramelized onion works so well in it as well as sundried tomatoes! Be free to experiment depending on your taste my friend!
I am so happy that you enjoyed my entry and i will make sure to be a regular contestant in such a lovely contest!
