Ground almonds, which are also sold as "almond flour" or "almond meal" (in case you prefer not to have to grind them yourself), are often used in baking everything from cookies to quick breads to pie doughs. Here, they are combined with regular flour, carob powder, sugar, and butter to make thumbprint cookies, which are filled with a dollop of fig jam (or your favorite flavor of jam) after baking and cooling.
