Thumbprint Cookies (Strawberry Rhubarb and Raspberry)

Last month, my cousin Jennifer brought cookies to my house, delightful little thumbprint cookies. They were perfect, with their jeweled colors and melt-in-your-mouth buttery goodness. But do you know what made them extraordinary? My husband loved them. My husband, who is indifferent to almost all baked goods known to man, not only ate them, but pronounced them his favorite cookie of all time.

Well.

That was that, as they say. I've never had any desire to make fruit thumbprints before (I inevitably lean towards cookies filled with chocolate etc), but I immediately requested the recipe from my cousin, so I could take a look at it. A little searching turned up the fact that this recipe originally came from the book Williams-Sonoma Collection: Cookies, under the moniker of "Ruby Jewels."
