For some things, lard is essential if you want it taste right. An example is piadina, an Italian flatbread from the Emilia-Romagna region. It's wonderful and pretty easy to make. You can make it with olive oil, but if you want it taste authentic, you must have lard. You can make biscuits and pie dough with butter instead of lard, but the difference in flavor is immediately noticeable. I will make this point, though: if you plan to buy and use lard, buy the smallest amount you can. It doesn't keep very long.
