Unusual food

What can be more tasty than fresh wheat bread with butter and red caviar? Nothing can be tastier! I know very FEW Russians who don't like red caviar. But I know one American who said that it would be his last hour in this world when he would try salted fish larvae. I never thought about caviar like that. We all eat eggs which were chicken embryos. And I started thinking how many unusual things Russians eat.
We don't eat fried fly larvae, fried tarantula or dried caterpillars or other terrible for us asian dishes (I still cannot believe that they eat dogs). But I found out that many people in the world don't eat chicken hearts or chicken stomach like we do. Russians like salted pork lard and jellied meat (pieces of meat in salted jelly with vegetables). A beef tongue, for example, is a delicacy in Russia. We drink a drink made from fermented horse milk and kissel (it is a viscous sour fruit drink with starch). Our northern nations eat deer meat (not only meat, everything that a deer has, heart, horns, liver, bone marrow etc. It is horrible, but we eat horse meat in some OF our republics! (In your Republic) We raise smart animals to kill and eat them. Dishes from horse meat ARE considered delicious food...
Anyway, I love red caviar! I could eat it everyday if it wasn't so expensive. And what unusual do you eat?
