This is my favorite spice mixture. There is almost nothing it doesn't taste good on or in. Use it to make spice-encrusted pork ribs, chops, or tenderloin; veal chops; chicken breasts; duck; beef; liver; or eggplant; or add a teaspoon to lentil soup.
Put the fennel seeds, coriander seeds, and peppercorns in a heavy pan over medium heat. Watch carefully, tossing frequently so the seeds toast evenly. When light brown and fragrant, pour the seeds onto a plate to cool. They must be cool before grinding, or they will gum up the blades.
Pour the seeds into a blender and add the salt. Blend to a fine powder, shaking the blender occasionally to redistribute the seeds. Store in a tightly sealed glass jar in a cool, dry place, or freeze.
