Add all ingredients except the poppyseeds to a small blender or food processor. Add 1/2 teaspoon lemon zest and blend until smooth.
Taste and adjust to preference. For a sweeter dressing, add 1–2 more tablespoons sugar.
Stir in the poppy seeds.
Transfer to an airtight container and refrigerate until ready to serve.
Notes
Note 1: I like to use both whole milk and heavy cream. If you’d rather buy just one, half-and-half works great in place of both.Storage: Dressing keeps well for up to 1 week in an airtight container in the fridge. Stir before serving.Nutrition Info: Based on 2 tablespoons (regular version). The recipe makes about 1 cup total. The lite version has 42 calories per serving.
