French walnut-coffee cake Cake "Opera" is a French flat cake consisting of layers of nut biscuit (in French - Gioconda), which are impregnated with coffee syrup, coffee-oil cream and ganache. In conclusion, it is glazed with chocolate. The French Dalloyau confectionery made the cake famous. About the creation of this cake there are 2 versions: confectioner Siriak Gavillon, working in the house of Dalloyau, invented the cake in 1955, the second says that Louise Clichy presented the same cake at the exhibition of cooking in Paris back in 1903. If you visit Paris, then in every restaurant you can try this tasty coffee cake. But it is not necessary to go on a trip to France, you can perfectly prepare such a hard, yet affordable cake.
