Fill a large pot with water (use hot faucet water to reduce time it takes to heat it up using circulator). Set circulator to 63 degrees celsius. When temperature reaches 63 degrees celsius, gently place whole eggs in water. Let eggs cook 45 minutes. Remove from pot and serve immediately, or place in ice bath to cool. Refrigerate whatever you don't use. To reheat, simply place eggs in warm water (I put them in water that's about 60 degrees celsius for 5 minutes).
