I love muffins and one of my favorite recipes is this one for strawberry shortcake muffins. I especially like that it is low in sugar so I feel slightly better about them. I use this same recipe to make blueberry muffins, but my father complained that they were too "dry.' Well I accidentally doubled the sugar once...and he loved them! So I make his that way now (I still use the regular amount for strawberry, it is just blueberry). So if you needed proof on why sugar is a "wet" ingredient, there you go!
As a note, I did try these once with raspberries, but I didn't like how the seeds were in them. The muffins were tasty, just felt that I was constantly picking seeds out of my teeth. I can eat raspberries plain, but in the muffin, it just didn't work for me.
