1 head peeled black garlic
3 Tbsp (1g) bonito flakes
1/2 pound (227g) unsalted butter, room temperature
Take 3 tablespoons of bonito flakes and roughly chop it. Repeat this process with 1-2 heads of peeled black garlic.
Add both of these ingredients to ½ pound of unsalted butter that is at room temperature. Mix it all together, then lay it down on a sheet of plastic wrap.
Rotate the plastic wrap around to create a sausage shape. Grab the ends and make sure there is no seam.
Roll your sausage shape against your counter over and over, allowing it to get tighter.
Tie off the ends and place in the fridge until completely firm.
