Combine the “chunky” spices (garlic, onion, oregano, sugar, salt, coriander, jalapeno) in a herb grinder, food processor or mortar and pestle. Pulse or crush until these become reduced by half. Be aware that the jalapeno may dust up, so avoid getting it in your eyes, or transferring it from your fingers to your eyes.
Transfer the crushed/processed herbs to a bowl and add remaining ingredients. Stir gently.
Move adobo seasoning blend to an airtight spice container with lid, preferably glass.
Best used within six weeks or keep in the freezer and remove only what you need for each recipe.
