So, I had some free time today and wanted to test my modifications in hopes of some success after so many failures. It seemed I was somewhat granted my wish...
I tried my best to minimize all possible sources of extraneous liquid. I drained and baked the mashed sweet potato, mashed the fresh blackberries through a strainer to squeeze out the water, strained the yogurt using paper towels (like a cheese cloth), and eliminated the vegetable oil. I also increased the baking powder. Lastly, I remembered to sprinkle some white sugar to help create a crispy crust.
After another round of investigation, I've gathered that the wholemeal flour may be contributing to the low rise as there's less gluten to help develop a stable puffed structure. I may indeed need baking soda since I have acidic ingredients that could be neutralized and help leaven the muffins some more. I may have actually overbaked the muffins, since I was so afraid of a soggy inside due to underbaking. I don't think I want to further reduce the liquid ratio as the muffin is showing potential for dryness; and frankly, I'm not sure how much more liquid I could eliminate.
One friend likes the muffins as is with the crunchy crust and soft inside. Another feels that the contrast is too drastic. A compromise may be difficult, but the ideal muffin texture in my mind is a thin hardened crust with an airy moist inside. My second attempt has neither a thin crust nor an airy inside. Maybe the third try will be it, but I'm definitely getting there as I'm running out of modification ideas...
