Prepare three milk mixture by whisking evaporated milk, sweetened condensed milk and heavy cream in a bowl. Add a very small amount of cardamom powder (if using), and taste. Adjust the flavor per your liking from there
In a clean dish (I used a 7x11" dish), stack ladyfingers tightly to create one layer. Fill any gaps by trimming ladyfingers.
Using a 1/4 cup measure, start drenching the ladyfingers. Make sure you get every one of them. You will use half of the milk mixture here. Don't worry if it looks like a lot, the ladyfingers will soak up the milk
Wait 10-20 minutes for the ladyfingers to soak up most of the milk mixture
Repeat with the second layer of ladyfingers
Place the dish in the fridge for ~2 hours
In the meanwhile, whip up heavy cream to stiff peaks
Spread half of the heavy cream on top of the ladyfingers, using an offset spatula to even it out
In the other half, add any food color of your liking (or don't). Transfer to a piping bag, and pipe to decorate. You can use any style of piping you like!
Decorate with crushed freeze dried strawberries and chopped pistachios
Serve and enjoy!
