Add 10 pieces sundried tomatoes, 2 garlic cloves, 60 ml vinegar, 1 tablespoon honey, ¼ teaspoon wholegrain mustard, salt, and 75 ml water to a small blender jar. Use the "pulse" function in short bursts to achieve a smooth dressing — or, alternatively, use the "slow" setting.
Add 60 ml extra virgin olive oil to the jar and pulse again to emulsify the dressing.
Adjust the seasoning to taste, and your sundried tomato dressing is ready to use.
Notes
It's crucial to add the olive oil last. If you add it too early, you run the risk of your sundried tomato dressing becoming bitter. It's also important for emulsification!
