Green Salad with Radishes and Creamy Mustard Dressing

In a medium saucepan, bring a few inches of water to a boil. Using a slotted spoon, gently lower in the eggs and cook for 9 minutes (or 8 minutes if you like the yolk a little softer). While the eggs cook, set up a bowl of ice water in the sink; transfer the just boiled eggs to the ice bath. Allow the eggs to cool in ice water, then peel them and separate the yolks from the whites. Reserve the whites for another use and push the yolks through a a sieve or a "spider" spatula into a medium mixing bowl. Add the mustard, vinegar, lemon juice, salt, and pepper; stir until smooth. Gradually whisk in the oil, creating a creamy, mayo-like emulsion with a bit more texture. Season and add additional lemon juice to taste.
