Like many inquisitive scientists, Kent Kirshenbaum regularly scans the ingredient list of prepared foods to uncover the chemical composites lurking within. The substance that most recently piqued the New York University chemistry professor's curiosity is liquid smoke. "My immediate thought was that it was a horrible mix of chemicals," he told us.

After distilling the concentrated smoke and liquid mix (often sold at the grocery store by the bottle to enhance barbecue) down to its roots of water and more than 400 chemical compounds, the scientist (who in person comes across as one part Einstein, one part Malcolm Gladwell) learned that liquid smoke is actually "safer [for human ingestion] than untreated wood smoke."

Kirshenbaum discussed his discovery last week during a monthly gathering of the Experimental Cuisine Collective -- food nerds who love to make things like edible foam. We caught up with him to chat smoke, bongs and homemade liquid smoke.

What is liquid smoke?
Liquid smoke is very simply smoke in water. Smoke usually comes as a vapor, but there are ways to condense it and turn it into liquid and that liquid can then be carried in water.
