henry ford, who revolutionized the american automobile industry, also invented what we all know today as charcoal briquettes........ he originally made his automobiles with large quantities of wood parts and ended up with a warehouse full of scraps........ ever the entrepreneur, ford came up with the idea of charring the discards and compressing them into briquettes..... for this job ford turned to his brother-in-law, E.G. Kingsford...... the new company sold the briquettes only at ford dealers until the 1950's, when a surge of interest in outdoor cooking and grilling prompted local grocery stores to start carrying ford's ingenious black briquettes...... although not a bit of new england history, I thought of those wondering WHERE the sooty squares came from.........
