What if you have no time? Like, the party is in six hours and you just woke up from a nap?
Here’s the cheat code: make the filling (mascarpone, yolks, sugar) the night before. Keep it in the fridge. The next day, just dip the ladyfingers and assemble.
It takes 15 minutes. Your filling is already chilled and stable. You’ll get a decent tiramisu in about four to six hours of chilling. Is it perfect? No. But it’s good enough. And sometimes good enough wins the day.
