What's up with all this piggy smelling lard? Lard shouldn't smell like that, even when heated to 325 degrees or more in an oven. Otherwise all the fine pastries in this world would smell like bacon. Mmmm bacon... But anyway lard has a relatively high smoke point compared to many other oils we use, and I'd have to question the quality of the product if it still smelled "piggy". It shouldn't taste piggy either. If your house smells like you're cooking a pork roast while baking apple pie at 350 degrees, it's a bad thing and there is something wrong. If I wouldn't use it to make pie crust, I'd certainly not use it in soap.
I've given away dozens of unscented, high percentage lard soaps, and not one person has noticed any pig odor in them. Lard should be snow white when solid, less color when melted compared to most vegetable oils, and have no to little distinctive odor even when you stick your nose in the bucket. It shouldn't taste stronger than vegetable shortening. It should be completely solid at room temperature. Even the cheapest processed brands like Tenderflake almost pass these criteria. Better is a good leaf lard.
Perhaps my nose isn't so great anymore, but everyone I've given it to wants more. That's why I would first consider the quality of the lard being used if soap made with lard smells "piggy".
Edit: But to address the subject of the thread, if I were blessed with a tub full of piggy smelling lard, I'd use the fragrance of at least 10% pine tar mixed with a minimum of 30 gr/kg of half and half cedarwood and lemongrass EO. Very yummy, and even if you got DOS you'd never notice!
