[Homemade] James Hoffman’s tiramisu

Don't have a sous vide machine so did the egg yolks in a Ziploc bag submerged in a rice cooker full of water on the keep warm cycle.

Also – don't judge this recipe until it's sat for 24 hours. After 2 hours it was 5/10, rose to a 9/10 by the next day. I don't really understand how.
