If you add eggs directly to hot liquid, you get lumps. To minimize this you need to temper your eggs before adding them. Here are the steps:
1. Beat your eggs very well
2. Stir 1 TBL of hot liquid into your eggs
3. Add a second, then a third.
4. Now, add a ladle full of hot liquid
5. Remember to stir constantly
6. THEN pour BACK into your hot liquid, again, remembering to stir constantly.
