Peel and cut your shallot in half, juice half a lemon, and cut your gorgonzola into large chunks.
Add all of your ingredients to a small bowl or wide-mouth mason jar.
Insert your immersion blender into the jar and blend until smooth and creamy.
Taste and add more salt, a pinch of black pepper, or a little more vinegar as needed.
Notes
Store in the fridge in an airtight container for 5-7 days. The gorgonzola vinaigrette may thicken when refrigerated due to the olive oil. Allow it to rest at room temperature for a while and stir or shake to combine.If you prefer a chunky blue cheese dressing, add in another 2-3 tablespoons of gorgonzola crumbles after you finish blending.
