Smoke-water and bulb growth

I describe in my book, 'Fall and Winter Bloom in the Solar Greenhouse', how I used a condiment called Liquid Smoke to help germinate Erica and Protea seed (prompted by an article in Rock Garden Quarterly).  With some species it meant a difference between zero seedlings and four or five of them.  Granted, it sounds like sympathetic magic, but there the plants are, still going strong.

I was thinking about using "smoke" method for erica and syncarpha vestita seeds 
South Africa to stimulate their germination.  How to prepare smoke water?  
Mixing with ashes?  
Thank you for your help.
