This is one of my all-time favorite salad dressings. I stared using light olive oil recently as I felt extra virgin was taking away from the wonderful truffle taste. Keep it simple with this dressing, the best lettuce and nothing else.
Ingredients:
2 1/2 TBSP white truffle oil
1 TBSP light olive oil
1 TBSP champagne vinegar
1/4 tsp lemon juice
1/2 tsp salt
Pepper
Combine in a small jar and shake.
