1. In the top of a double boiler or metal bowl (4 to 6 qt.), whisk to blend egg yolks, sugar, lemon juice, and Riesling.
2. Set double boiler over boiling water, or nest bowl in a pan over boiling water. Whisk egg mixture (or beat with a mixer on medium speed) until it is thick enough to hold a mound for a few seconds, 5 to 7 minutes total. Add lemon verbena, whisk, and serve at once.
