Some foods are used to satiate the stomach, which is a must, such as crude tea and meal: although the taste is plain, but indispensable, also eat for a long time; some foods are used to provoke taste buds, will bring unexpected surprises, with surprises, like a little romance in ordinary life! But at the same time, a little of this kind of food is enough, and it will get tired if you eat too much. Now lets get to the point. This Russian Thousand-Layer Cake, named Napoleon of Russia and Tiramisu of Russia, has nothing to do with Tiramisu. Napoleon is more appropriate. Napoleon cake has nothing to do with the French emperor Napoleon. One of the reasons is that its English name Napoleon is actually a misunderstanding of Napolitain. It refers to a crispy name from Naples, Italy. The French name Mille-feuille has been written as Napoleon. Napoleon cake is expensive. It not only uses complicated crisp technology, but also has rich sandwiches between crisps, including not only fresh butter, but also cheese sauce. Today, I made this Russian Napoleon cake, which has a very rich taste, crisp "Thousand Layers" cake, sandwiched with egg yolk cushmus. It is not as complicated as the French Thousand Layers Crisp, which requires repeated refrigeration, folding and rolling. It only takes several processes to achieve the best taste, at least three days. If you ask me: Is it worth the trouble just for a few bites? Ha ha, I can only answer this: different environments have different mentalities, different people have different values, you think value is worth it!
