Moo's Cauliflower Salad

This is a vegetable salad of cauliflower, celery and onion (I think you could easily add some sliced carrots too). Moo received this recipe from a friend, but she then took the recipe apart and recreated it. The lemon dressing makes it a Moo palate pleaser.

fresh cauliflower, sliced
celery, sliced
raw onion, chopped
salt & pepper

Lemon Dressing
2 large lemons, use juice of both and grated rind of one
2 T sugar
3 large egg yolks, slightly beaten
1/2 t. salt
1/4 t. pepper
1 cup sour cream

Lightly beat the egg yolks and set aside. Combine lemon juice, sugar, salt and pepper. Reserve the rind. Bring ingredients slowly to a boil, swirling the pan to dissolve the sugar. Stir a little of the hot juice into the egg yolks to warm them. Return all the egg mixture to the juice saucepan over low heat. Whisk briskly until the eggs have thickened slightly. Remove from heat and immediately whisk in sour cream and rind. Set aside to cool to room temperature.

Pour over vegetables, mix well and serve.
