How do I get a burned smell out of my house?

I was steaming artichokes in a copper/steel pan, took my dogs for a walk, and came in and the pan was burned dry, the house was full of smoke, and I cannot seem to get the awful smell out.

Here is what I tried:

Exhaust fan plus central air exchange with windows open

Got the pan out of the house after I realized the smell wasn't washing off.

Burned a soy candle for awhile.

Used Febreze spray. (That worked best.)

Started a load of laundry and dishwasher to get good smells going.

Put a small pot of water on the stove with whole Christmas spices to freshen the air.

Its been about an hour, and the smoke is gone, but the smell is still strong, and now ther are several competing smells. We live in Michigan, and its not really warm enough to keep the windows open. Any other ideas?
