I've always been curious about trying this, but not knowing any Hungarians, I'm unsure about how to make it. Some recipes say to include tomatoes, others say no tomatoes whatsoever. Some call for flour, when others say to use potato. Some call for a few teaspoonfuls of paprika. Other's call for half a cup. Sweet or spicy? I don't think I've seen so much variety in how to cook what I thought was a "national dish". I have a few pounds of cubed lean beef thawing in the fridge - what's your best goulash recipe?
