I had such high hopes for these, but they failed me on various levels:
1) My crumbs were runny, turning to crusty when the muffins cooled.
2) The muffins were excellent warm, but kind of dry when they cooled off. I needed coffee to go with them later in the week. Would the lemon zest have made a difference? I didn’t have any in the house!
3) Without the crumbs, the muffins were kind of dull. Nice with coffee, but not the kind of thing I was eager to eat in the car on the way to the train in the morning.
But I have high hopes for the sweet potato biscuits I’ll make Sunday when I return from Nashville!
