Using dedicated ice cube trays (don't use the trays for ice cubes after using for sofrito or your drink will taste BAD!), freeze sofrito in cubes, then, if desired, transfer to freezer bags for long term storage. Each cube is about a tablespoon, but measuring is not super important. Flavor is good, give or take a little! Fresh sofrito lasts about a week in the fridge. Just pop a cube or two or 3 into your saute pan to start your cooking, or thaw and stuff under chicken skin before roasting. The possibilities are endless!
