Buying advice
1) Cook eggs in-shell at 145°F for 45 minutes. 2) Ice-bath and peel carefully. 3) Marinate 4-24 hours in soy, mirin, and a little sugar (add dashi or garlic if you like). 4) Halve and place over ramen.
FAQ
What temperature for ramen eggs?
145°F (63°C) for 45 minutes — custardy, jammy yolks.
How long should I marinate?
4 hours for a light flavor, up to 24 hours for a deeper soy permeation — don't overdo it or they get salty.
Do I need mirin?
It balances the soy with sweetness — substitute a pinch of sugar if you don't have it.
