Yes, thank you for the reminder: bread and dripping sandwich reminds me that food is precious and waste not part of our food legacy. I did not yet mention the form of lard known as "asiento". It is somewhat reminiscent in color to the drippings left in the skillet when you make bacon -- for Mexicans it is commonly smeared on tortillas for a fortifying bite -- not unlike the wonder food of pemmican. Crows would probably also enjoy a tortilla with "asiento".
