I slightly changed a cookie recipe at work and it was a change for the better!
Have you tried soaking raisins in rum before adding them to the oatmeal raisin cookies? Really tasty.
Rum...
Actually these were hermit cookies, and I increased the molasses from 1.5 cups to 2 cups.
It made them softer, chewier and more flavorful. I am still happy about that, it made my day.
