Pure lard is especially useful for cooking since it produces very
little smoke when heated and has a distinct and pleasant taste when
combined with other foods.

Many chefs state that lard is a superior culinary fat in terms of
its possible applications and its taste. Lard does not contain any
trans fat.

Because of its higher melting point, pie crusts made with lard tend
to be more flaky than those made with butter. Many cooks employ both
types of fat in their pastries to improve the product's texture and
flavour.

Lard is one of the few edible oils with a relatively high smoke
point, which is because of its high saturated fatty acids content.In
the United States, use has declined with the introduction and
popularization of Crisco (cottonseed oil ) .

Lard sandwich (in Hungarian "Zsíroskenyér" or "Zsírosdeszka", in
German "Schmalzbrot") often topped with onions, and generally served
with salt, and paprika is popular in several Earopean countries, and
generally eaten with beer[1].
