When making tiramisu you should not over soak the ladyfingers, over whip the mascarpone until it breaks and separates and don't skip the mandatory and required 4 hour to 24 hour chilling period when making tiramisu.
Don't leave the ladyfingers for tiramisu in coffee too long as they are long sponges and if left in the coffee too long they will turn into a puddle and mush.
Submerge the ladyfingers in the coffee for only 1 to 2 seconds per side.
And don't use hot coffee or sugary coffee as the coffee must not be sugary and must be at room temperature before dipping as hot coffee will melt the cream and coffee with sugar will clash with the natural balance of the tiramisu.
Also don't over mix the mascarpone and instead whisk the mascarpone until it's just smooth and combined.
Mascarpone is also high in fat, whipping the mascarpone too much also causes the fat to solidify or curdle, which results in a grainy texture.
And when combining the egg yolks with sugar, mix them immediately and when incorporating the whipped cream or egg whites, gently fold them in with a spatula, instead of using a vigorous stirring motion, which will also deflate the air.
And don't use cold mascarpone and instead let the mascarpone sit on the counter for around 10 minutes before you use it, as cold cheese is stiff and much more prone to over mixing.
Also don't dust the cocoa powder too early and instead dust the top of the tiramisu with cocoa powder right before serving, because if you dust the tiramisu and leave it to sit in the refrigerator, the cocoa will absorb moisture from the cream and turn into an unappetizing dark paste.
Tiramisu also requires at least 4 hours and preferably 24 hours to 36 hours in the refrigerator, which allows the sponge like ladyfingers to meld with the cream properly and firm up the tiramisu dessert so that it can be sliced cleanly.
What makes a bad tiramisu are mushy lady fingers, runny or curdled cream base as well as poorly balanced coffee and alcohol flavors.
Because tiramisu is a no bake dessert, the success of making a good tiramisu relies entirely on ingredient management and texturing techniques.
Structural and texture failures that can lead to a bad tiramisu include.
Soup, runny cream as a runny filling happens when you add extra liquids directly to the cheese mixture, over whip the eggs or if you forget to chill the tiramisu for at least 6 hours to 24 hours to allow it to set.
Overwhipped or split mascarpone: Mascarpone has massive fat content and if it's whipped for too long, too fast or at warm temperatures the mascarpone splits into tiny, grainy beads of butter.
Using the wrong cookies or ladyfingers: Authentic tiramisu requires crunchy Italian Savoiardi and using soft, cake style ladyfingers makes the tiramisu dessert dissolve into mush instantly.
And leaving the ladyfingers in the coffee too long for more than 1 or 2 seconds turns the ladyfingers into a mushy and watery mess as they will leak excess liquid into the tiramisu dessert and destroy the clean layers.
For flavor and ingredient flaws that make a bad tiramisu these include.
Improper cocoa dusting: Dusting the cocoa powder too early causes it to absorb moisture from the cream, which turns into a wet, dark sludge instead of a light, velvet coating.
Heavy handled alcohol: Adding too much alcohol like rum, brandy or Amaretto overpowers the delicate cocoa and espresso flavors and adds excess moisture that thins out the cream.
substituting cream cheese: Replacing high quality Italian mascarpone cheese with regular cream cheese makes the tiramisu dessert taste heavy, tangy and flatly rancid, instead of velvety and rich.
And using bland or acidic coffee as filtered coffee, instant coffee or cheap coffee pods lack the depth that is needed to pierce through the heavy dairy.
Stale or burnt espresso, leaves a bitter and unpleasant aftertaste.
The ladyfingers that are best for tiramisu are authentic Italian ladyfingers called Savoiardi, which include Pavesini ladyfingers, Forno Bonomi ladyfingers and Vicenzovo by Matilde Vicenzi ladyfingers.
Pavesini ladyfingers are a much thinner and crispy cookie alternative and because they are so thin, they also virtually melt into the cream layers and yield an incredibly fluffy result.
Forno Bonomi ladyfingers are a classic Italian brand of ladyfingers that are approved by the Italian Chefs Federation.
They are firm, dry and are baked for a perfect absorbent bite and you can easily find them on Supermarket Italy.
Vicenzovo by Matilde Vicenzi lady fingers are known as the number 1 ladyfinger in Italy and feature high quality flours and eggs, which soak up liquid evenly while holding their shape beautifuly, which makes them ideal for a make ahead dessert and they can often be on Amazon as well.
Italians do not put alcohol in their tiramisu, although some Italian restaurants do use alcohol in their tiramisu.
The original and strictly authentic Italian tiramisu does not contain any alcohol.
Adding alcohol and spirits has become very popular worldwide as a modern trend when making tiramisu, but traditional purists in Italy and even the official guidelines for the Tiramisu World Cup in Veneto all exclude alcohol from the tiramisu completely.
The original tiramisu dish relies strictly on just 6 basic ingredients which include.
Unsweetened Cocoa Powder.
Strong espresso coffee.
Sugar.
Egg Yolk and sometimes whipped egg whites.
Mascarpone cheese.
And Savoiardi also known as ladyfinger biscuits.
And despite the strict historical recipe for tiramisu, many people at home and contemporary restaurants across Italy do choose to add a splash of alcohol to enhance the flavor of the tiramisu.
But if alcohol is used in the tiramisu dish, it is often mixed directly into the espresso that is used for soaking the ladyfingers or whisked into the egg yolks.
The most common alcohols that are used in tiramisu are Marsala Wine, Dark Rum or Brandy and even Amaretto.
Amaretto is an almond liqueur that complements the bitter cocoa and sweet cream.
Dark Rum or Brandy is used to deepen the punchy kick of the espresso.
And Marsala wine is a Sicilian fortified wine that adds a sweet and nutty undertone and is the most widely accepted boozy addition to the tiramisu by Italians who use alcohol in their tiramisu.
