Last week Wednesday, I got up in the morning, wandered into the kitchen and had the sudden urge to bake apple streusel tartlets. I wanted to switch things up from my usual French apple tarts. Omitting the almond paste adding streusel seemed like a good start. Except, I had never baked streusel anything before. But I was in an experimental mood, so instead of looking up a cohesive recipe, I combined base recipes instead.
