I've got some espresso grind coffee infusing in canola oil. It's been sitting for about a week now in a cool, dark cabinet, and I give the jar a good shake once a day. Smells pretty good, and I think I can use some of the grounds in soaps, too since it's a very fine grind. I used a full 8 oz package of ground coffee (been kicking around in my freezer for longer than I'm willing to admit, but was vacuum packed- smelled okay when I opened it) in a quart jar, with as much canola oil as I could fit into the jar plus about an ounce of vit E. I plan freeze a few blocks of mostly grounds to use in soaps. My tiny little rose molds might actually work ok for this, they hold about a tablespoon each. What I'm wondering if anyone knows is, will the scent survive the lye monster in soap? How about usage rate on the infused oil? Would 2 oz PPO be too much? Not enough? Would using brewed coffee as my liquid help, or be overkill? Can I add more oil to the infusion jar and keep that going since I used so much coffee in it to begin with?
