Place the white beans in a small bowl and smash them with a fork.
Crush fennel seeds, rosemary, thyme, and red pepper flakes with a mortar and pestle.
In large bowl, whisk together all dry ingredients, including those you just crushed with the mortar and pestle.
Mix in the smashed beans. The easiest way to do this is with a pastry cutter.
In a small bowl, mix together all wet ingredients.
Add the wet ingredients to the dry ingredients, mixing and kneading for about 3 minutes.
Form sausages and wrap each in a layer of parchment paper and then a double layer of foil. Twist the ends of the foil tootsie roll style. My sausage links are approximately 3 to 3 1/2 inches long and about 3/4 inch diameter. If you make larger sausages, you will need to adjust the cooking time.
Cook in steamer 30 minutes (45 minutes for large sausages).
Let the sausages cool completely.
To serve, fry in a non-stick pan to brown.
