Introduction
This is a quick recipe that would be perfect as a Christmas or birthday dessert. Start to finish it takes about 45 minutes or so, with a third of that time for roasting the marrow bones.
It is easily modifiable to create something that suits your diet. A more savory version could be created by nixing the spices and sweetener, a non-dairy version could be created for omnivores by swapping heavy cream for coconut cream, spices could be changed to suit your preference – go hog wild! I take recipes as suggestions, not hard and fast guidelines. Just be aware if you change the recipe and dislike it – I’m not responsible!
One small note I’d add is not to use granulated erythritol, as it tends to re-crystalize after cooling. Sweetener amounts will vary depending on what you’re using.
Materials
3 Marrow Bones, raw
1 tsp ground cinnamon
1 tsp cardamom
2 pinches of saffron
1 cup of heavy cream
1/4 tsp vanilla extract
1.5 tbsp confectioner’s swerve (depending on preference)
(Optional) 28g cocoa butter
1 tsp gelatin
Methods
- Preheat oven to 450 F (230 C)
- Roast marrow bones on a baking sheet for 15-20 minutes once oven is to temperature
- Remove marrow bones from oven and place a wire rack on the baking sheet with the marrow bones on top while they cool.
- This allows the fat to collect in the pan for later use.
- Once the marrow bones are cool, empty the marrow into a separate bowl using a chopstick or similar to swirl around the inside of the bone to easily remove the marrow, or use your preferred method.
- 3 marrow bones gave me about 2.2 ounces of marrow and residual fat
- Pour the fat (about a tablespoon) from the baking sheet into a medium sized saucepan on low heat, coating the entirety of the bottom of the pan
- Add your spices to the marrow fat and roast on low heat (being careful not to burn them!) until fragrant
- Add heavy cream and stir until spices are thoroughly incorporated (be careful not to scorch or boil the cream – be sure to stir constantly)
- Add vanilla extract and confectioners swerve
- (Optional) Add cocoa butter, stirring until melted
- Pour cream into bowl with bone marrow and use immersion blender until completely smooth, being careful not to whip the cream (a food processor or blender can also be used)
- Pour cream mixture through a fine mesh strainer, back into the saucepan, to ensure there are no lumps
- Add gelatin, gently whisking on low heat to incorporate into cream mixture for 1-2 minutes
- Pour cream mixture evenly into three ramekins or molds
- Refrigerate until completely set (usually 4 hours or overnight)
- Eat!
Results
The bone marrow panna cotta does not have a strong marrow taste. With cocoa butter the taste is very chocolate-y, and without cocoa butter it is more of a cinnamon swirl flavor. The texture is creamy, and it is very rich. It is loaded with animal fats (plus cocoa butter if you opt for it), particularly saturated fat, so it makes a nice, small, dessert.
I don’t particular like to cook unless I have company, so this is something I’d keep to holidays and special occasions. But if you have marrow bones laying around and you need something to do with them besides eating them roasted, or in bone broth, perhaps this is something you could give a try.
Background
One day on twitter there was a little happy accident. This happy accident was seeing the below image while browsing through Twitter and misreading the slogan as “When the desire for marrow-based confection prevails[…]”
Upon re-reading and realized I’d misread a rather crucial word, I then gave a little thought to the concept of a marrow-based confection. Could such a thing be possible? Should such a thing be possible? After a while I decided bone marrow panna cotta may be the perfect way to achieve such a thing. After looking up various panna cotta recipes to get a feel for what they generally consist of, and a couple of test runs, the above recipe came to be.
If you decide to try out (or modify) this recipe, let me know how it turns out! Have suggestions for improvement? Know of a way to make, e.g., a dairy free carnivore version? Put your own spin on the recipe? Let me know below!
