The microwave? Sounds kinda radical to me. I like the idea of filling fresh from the dishwasher although it would greatly surprise me if even that amount of attention to sanitation is really necessary. Although I have no long term proof that my method works, I have little doubt it will be fine. I take clean jars and new lids, fill them, packing fairly tightly so as to minimize air and required cellaring space. Put on the lid, minus the ring, suck out the air using a Foodsaver jar adapter, test the seal, screw on the ring and store. Foodsavers are routinely at thrift stores for $15 or so, by the way. The jar adapters are available for both standard and wide mouth lids and is about $15, new.
