For pine tar soaps I recommend using full water, soaping relatively cool and melting your pine tar with some reserved oil from your batch and adding the tar/oil mix at trace. Don't try to stickblend the tar/oil mixture into the traced soap, it's better to whisk it by hand. I've noticed that PT soap takes longer to cure, it will feel pretty sticky for a while, especially if you use a large percentage of pine tar. Nothing will cover that scent, but it does mellow over time to something almost pleasant.
