Blackberry Jam Cake is a family tradition passed down from my mom's family. It's a southern dessert, representative of my mom's upbringing just south of Nashville, Tennessee. The cake has a little sugar, but not much. Most of the sweetness comes from the jam, which no doubt would have been homemade using wild blackberries picked in the summer.
My mom loved picking blackberries as a child. She wore her brother's overalls and long sleeve shirts, a pragmatic concession to the strict rule that girls should only wear dresses. They took buckets with them and picked all day. The purplish stains around their mouths betrayed their claims that all berries went in the bucket. As mom admitted, the warm berries were too hard to resist and they often ate enough to make them sick to their stomachs while they picked.
Her mom made the blackberry jam cake for Christmas. It, along with a wheel of cheddar cheese that they enjoyed with their morning biscuits, was a special treat, a cake too expensive to make more than once a year, but a Christmas staple. My mom brought the tradition to our house. Even after we grew up and left the house, my mom would make each of us a jam cake for Christmas. I've been known to freeze pieces of mine before it got stale to have for later in the year.
The cake is quite moist, and resembles a spice cake in flavor. The nuts and raisins add great flavor. As you can see from the recipe above, she did not specify what nuts to use. As I recall, she just used what she had on hand. Often at Christmas time, we had black walnuts, English walnuts, and pecans around the house, either to eat as a snack or to use in baking. I remember loving the distinct flavor of the black walnuts in the cake.
My brother texted me on Friday night saying, "I wish I could share a piece of my jam cake with you." I'm not sure how he knew I was craving it at the moment. I had already pulled the recipe out earlier that day. His wife took up the tradition several years ago. I called her yesterday for some pointers. I'm glad I did. As is often the case with my mom's recipes, there were things missing, nothing especially important, but little tips that help make it a better cake baking experience.
