The problem is that sugar pearls are hard to come by in the states. But I think I came up with a good solution. I decided to take sugar cubes and break them up. Not into dust, but into chunks. If the sugar is too small it will just incorporate into the dough. But the chunks won't, and will leave little pockets of caramelized sugar. It's the most delicious waffle ever.
Another issue is I didn't have ground almonds as some recipes I saw called for. I substituted with ground flax. But I'm sure you can use either one or leave it out completely.
These aren't waffles you can just whip up last minute, you have to let the dough rise 3 times. But you can freeze the dough and pull them out later to make. These are special occasion waffles for sure. But well worth the work!
You've got to make these! You won't regret it. Let us know if you do in the comments and what you think!
