Today I'm not offering you a classic recipe, but a little gourmet tutorial: Austrian-style Gentlemen's Torte. This preparation, also known as Sandwich Cake, exists in many countries with local variations. In France, the Swedish version with cucumber, salmon and chives is particularly popular. The principle is simple: superimpose layers of bread, various fillings and seasonings, then cover the whole thing like a savoury cake. The result is a spectacular and convivial starter, perfect for a buffet, brunch or family celebration.
